I think the current game mechanics are heavily in favor of attackers. They have got gems, they can use invocations, they have to pay nominal ambrosias to ressurect, voila.
My sugesstions :-
- once a hero dies in battle, his cooldowns should not be refreshed upon ressurections or better yet, they should be increased by 50% i.e Helen dies when Helen’s Beauty has 10 seconds left on cool down, after ressurection her CD now stands at 20 seconds
- increase ambrosia cost for ressurections by a little
- reduce the number of times someone can ressurect
The current mechanics actually encourage attackers that they die, spend 50 ambrosia and pop all CDs again, your prime example : Helen.
Thankyou for your time.
