I feel like raids are too depended on initial board. Can you make specials before enemy does? if not, you are basically in most cases already too much behind.
Damaging specials hits too hard for HP heroes have…
I dont think one special should take down a LEGENDARY HERO ? (or barely survive).
Bad/good boards effect could be reduced if hit points of champions would get doubled and healing would be reduced by 50% (not mine idea, but it reasonate with me most, so I would like to give it a bit more push).
This is mostly noticable only in raids and wars, so other parts of game dont need to be touched.
Basic general vision to me would be if legendary sniper shoots special at :
- rare (3* hero get 1 shotted (some) or ( most) barely survives)
- epic (4* hero requires 2 specials or 1 and half)
- legendary (5* star requires 2,5 or 3 specials )
This would give reduce effect of bad boards or games where you completely dominate, and give you some more time for strategy.
