EDIT: I meant to put this in the feedback forum - was it moved here by a mod or did I misclick?
Currently, shadows are underpowered - I don't expect to see any dispute on that. I personally believe they are THE weakest class but some may argue for guardian. Let's explore what makes shadows so weak and try to figure out what could fix them.
First, lets compare Kai Samurai (highest def shadow class) vs. Cybella Royal Huntsman (highest def ranger class) just to highlight the stat weaknesses:
Lvl 30 Stats w/ Zeus faith
Kai Cybella
ATK 1489 1858
DEF 1735 1612
HP 3766 3766
CRIT 1243 751
MAG 381 628
What you can gather from above:
1) Cybella does about 25% more damage.
2) Cybella would take a small amount more damage per attack except she gets a 25%+ damage reduction from not being in the front line.
3) Same HP.
4) Kai has about 5% more crit chance (if the crit formula assuptions posted on the board are to believed). This means 5% of the time he would do about 20% more damage in a round than Cybella (single hit) assuming he is positioned right.
5) Both units will die to pretty much any spell but Kai is a little easier to kill.
Kai does get a combo attack but the damage drops off significantly between each hit, it is inferior to just plain ranged in nearly all situations.
Aura:
Kai - When others attack, 40% chance to inflict 65% of crit as poison damage for 2 rounds
Cybella - On crit (which can be brought up to perhaps 40+% if you focus on it), 70% chance to trigger others in aura (potentially 3 units) to attack with 50% ATK and knockback
Kai's seems alright at first glance but in practice it is lousy. It scales off CRIT which happens to be the hardest stat to raise - ATK focused champions can achieve over 9K ATK but CRIT focused shadows have a hard time getting over 4k... this is because it is the lowest base stat on average and gear/runes give the lowest amount of it. The damage this poison does is really low compared to the MAG scaling poisons of mystics and healers.
Cybella's may trigger less frequently but it has a lot more utility - some decent damage and knockback which could be great in an all ranged team.
Specials:
Kai - 150% CRIT as magic damage in X pattern, 30% MAG reduction for 2 turns, 35% DEF reduction for 2 turns.
Cybella - Self buff crit 15% (2 turns), force enemies to target other heros (3 turns, not in arena), 3 turn 30% damage reduction to target hero. 6 turn cooldown.
Again, Kai's special looks okay but then you see it is scaled of CRIT which we already know is low. This special glances off mystics and healers and does okay damage to others but still not 1 shot level like most other special attacks. The DEF/MAG haven't proven useful to me yet, perhaps because they last only 2 turns... I think this should be bumped to 3 or even 4 turns to give you a chance to take advantage of them. Keep in mind that 35% DEF debuff is not as amazing as it sounds with this damage formula... A 8000 ATK hit vs 3000 DEF would do an additional 1050 damage (5000 -> 6050) which is good but not amazing - definitely not better than just blowing them away with a high damage special.
Cybella's special is a rare non-damaging one and probably is very situational but I think may be preferable to a marginally damaging one like Kai's in most cases.
Conclusion:
Comparing Kai's various forms to Cybella's across the board has Cybella coming out on top. Having overall weak ATK (Kai Samauri is ranked 51 worst of all 58 5* units.) AND okay DEF (23/58) yet forced to fight melee makes them perhaps the least feared units in the game... And they don't seem to have any killer auras or specials to make up for their weaknesses either.
What can we do to fix shadows?
- Allow shadows to attack at range 3 tiles (shuriken?). This would mean a front row shadow can hit a second row oppsing unit in the arena. Keep in mind that his damage is still low, tied with healer class ATK.
- Have shadow specials cause physical damage instead of magic damage (and adjust multiplier accordingly) - this would result in more damage vs healers and mystics but less against champions and guardians... this seems to fit their theme better.
- Significantly lower the cooldown of specials that involve swapping places or warping enemies (this includes the healer warp specials). These specials are useful when they can disrupt the enemy (e.g. break an aura chain, move an enemy to melee range) but because the cooldown is so high, they rarely make a difference. The damage could be lowered to compensate (perhaps 3 turn cooldown, deals 125% damage)
