I have 6 Kiera sitting in my tavern. Now I just confirmed that I will never use her. Changing numbers in skill/aura is not a revamp.
Her MW form have a skill CD of 5, which means she will never cast her skill before zoey's skill delay. And since she's skill delayed, she will never cast skill before zoey cast her second skill delay... thus Kiera will be skill delayed forever...
Her RM improve makes no difference. She will still be targeted by enemy merlock and die before she can cast skill. Her aura is useless since it's mag based.
Her Ele ... same as RM, die before she has a chance to cast skill, and mag based aura is useless.
Her WL is improved, but confuse is not a very helpful debuff, no immediate effect. Merlock or Zoey WL are still better.
In conclusion, maybe it's more practical to wait for kiera insignia, since zedd insignia seems good.
make mages' skill based on def instead of mag, will make them more useful...
current meta is just stack def on mage, so merlin/zoey is the strongest because their skill/aura doesn't rely on mag, so they can just stack def...

Thanks for @Miyu point out my mistake... I have to say I know little about kiera, because my kiera are still all in 3* form.
I'm personally not very competitive in pvp, and my healer trigger team is basically a pve team.
so now let's just review kiera revamp again.
Firstly, we seems all agree that kiera, as a mystic, is mainly used in pvp...so we just discuss pvp fight.
Secondly, we all agree that Kiera should be weaker than Zoey, which although I personally disagree, but this is a pay-to-win game, cash hero always better.
Kiera MW is actually a weaker version of Zoey MW(Poor man's Zeoy MW), with 1 turn longer in skill CD. max 6 turn skill delay for a 5 turn CD means she can be used to infinite skill delay one target just like Zoey MW. Kiera MW's aura is also good since you can use her as utility mage(mages that do not need high mag to do the work), just stack def and make use of her on-hit skill delay aura.
However, Zoey MW is still a direct counter to her. Considering the popularity of zoey in top arena players, I highly doubt if it is really worth building a lv40 Kiera MW.(But a lv30 one with 15tp in def should be good enough to do the work)
Kiera RM is the most used form in arena before revamp, which I believe that means Kiera RM is fairly strong compared to her other forms. The improvement seems not much but actually makes a difference. 1 turn shorter CD makes it possible to use her skill in first round (if you go second, and you are not facing Zeoy MW), knock back 2.0 makes her damage higher(although skill damage is reduced by half in arena, and also reduce by enemy def). Her aura is not changed as it is already good enough, and pairs well with Zoey Ele and Lucille Inq.
I do not think anyone will use Kiera RM merely for the aura since you have better def aura like Darrion HD, but considering her knock back and high skill damage to all enemy, and being ranged, she's a better choice for some squads.
However, I just want to point out one thing. To make Kiera RM work, you need high mag, which means you are less tanky than those mages who stack def. This may or may not be a problem depending squad composition, but definitely something need to be take into consideration.
Kiera Ele's skill changed to burst damage output, skill overdrive is more useful(add 30% mag damage now) and burn 20% hp is a counter to high def enemies in arena. 5 turn skill CD is good just as said in RM section, if you go second and you are not facing Zoey MW.
However, same as her RM form, Kiera ele need high mag to work well, which means she's less tanky. But the same problem happens to Zoey Ele as well, so it's more of a problem from the class design than from Kiera as a hero.
This is the most exciting change. Her WL changed so much that actually changed how she works. Shorter Cd with a less damage is what most player asked for. Added on-hit confusion effect brings her in line with WL zoey. However, the problem is confusion is far less useful than stun. It does nothing on current turn and an on-hit aura should at least interrupt enemy attack chain, like merlin's fear and Zoey's stun.
To conclude, this revamp doesn't make Kiera as strong as Zoey, but rather a poor man's version of Zoey for most of her forms. Honestly I'm not expecting Kiera will be equal to Zeoy in strength, but wanting something unique to Kiera(which provides a reason to use keira even if you have zoey).
Two things I am expecting,
one is a utility focused form which allow us to stack def on keira while still make her do her work. which is half achieved. Her MW and WL is actually utility focused and can work in this way. But Zoey is just a better choice, which makes the only reason to use her is not having a Zeoy.
The other one is something makes Kiera unique, like Lucille Inq's 100% damage reduction buff. And we got on-hit confusion...
I apology for my offensive words but I still didn't find a use for kiera...basically wherever you need a kiera, put a zoey is better(probably except RM since Kiera RM is an upgrade from Zedd RM).
Now I see the problem is not with kiera, she's actually innocent and did her best to fight for her place in a squad. But she just cannot compete with a pay-to-win hero as a f2p friendly valiant hero.
Maybe when dark lord archer is released, our Kane GR will sit on bench and collect dust as well, Valiants is no longer the valiants we know. We are now even accepted the fact that valiant are no longer the strongest hero in Arathos... not any more. If a valiant cannot catch up with dark lord even immediately after revamp, when will she/he be able to fight equally against dark lord?
I don't mind to pay cash to make my life(in arathos) easier, I'm proud I can at least support a game we all love. But I don't really feel happy to compete with people using my pay-to-win stuff. There's just no honor in it. I'm not saying I dislike zoey, I just dislike the concept to make a direct upgrade version of hero like aladdin to kai. Everyone should be unique and we can have a reason to use her/him due to the uniqueness, even if it's an old hero(i.e. Luna MM).
That's all my words, not mean to offend anyone, just to express my idea of valiant revamp...
