Hi there my favourite forum goers! MiloD here to share some personal thoughts regarding Hero Merge...
I've questioned the developers myself regarding their choice of drop rates and they told me to really think hard about it.
Thus I went back and did some home work and realized something pretty important.
1. The gacha rate for a 5* hero via 400 gems is pretty damn terrible (like what? 0.1%? Yes I understand you can still get 5* potential heroes)
2. The cost of getting a random 5* hero flatly via Valianite is 15. (2000 gems minimum - 50 random heroes)
3. The cost of getting a 5* hero from hero merge is: low chance to drop + 86 5* XP pots + 2 4* +2 heroes
4. The cost of training up a 5* hero from 3* potential is obviously the best: 70 job keys over X days, with fodders to boot. You need to obtain this first though!
Then I realized why the hero merge was designed this way. It's not supposed to be easy and cheap. But yet it actually provides a cheaper free alternative way to obtain 5* heroes. You can even do it concurrently while upgrading your heroes IF you can afford it. Especially on Sundays between 6-10pm.
Think about it this way: Previously, the XP pots from Tower of Despair was almost useless. Now there's use for farming there again.
Hoarding tons and tons of XP pots previously can also now be utilized this way. If you're worried about not having enough for your current heroes to upgrade, you can manage your resources too.
This is why MiloD as an admin felt a large tinge of sadness by the response from the community. However, your frustrations are not without reason, because releasing the feature obviously meant we want you guys to use it. Thus I went to fight very hard to at least reduce the XP required.
MiloD would like to apologize to everyone on behalf of the developers. It's not that we are lazy and choose to release a poor feature. It's that we wanted to give players an alternative option to obtain heroes another way. I hope you guys see where I am coming from as well
