1 - I setup a team for dungeon, that team kills 3 out of 4 enemies, the last one self-buffs [Block Damage] but he is slow, what I have seen ? my champs attacked him 16 times for nothing till he spends his buff, such stupid monkeys. What if I do it manually (*) ?

2 - I setup a team for arena, enemies turn on [Block Damage] buff for 2 turns, my team auto lose. What if I do it manually (**) ?

3 - Re-think about all champs we have in inventory, look like 95% champs from epic down to common will become stupid monkeys against [Block Damage] buff, about 80 - 90% (??) legendary champs will become stupid monkeys in this case. 

4 - What if I do it manually (*) & (**) ? Nothing I can do, no other choice, the best I can do is use A1 to save A2, A3 skills. 

5 - Let make it more realistic, what will I (you) do when enemy invulnerable in 20 minutes ? I would defend and wait for 20 minutes (or run, if it is an option, lol, but I will come back after 20 minutes).

6 - Could developer let those monkeys less stupid or let me have a better choice in this case, but how ? 

a) A0 = defend stance: switch to defend stance, increase 30 - 50% def, increase 10-20% health. 

b) Auto choice, if attack does no damage to all enemies, then defend stance. 

c) Manual, have A0 option for all champs.

That is all I want to say, cheers!
