i vote for (too late since you putted the other part of the poll later on) new creature with drain ability
Mur mentioned all attackers are overpowering, and he will modify chaos archer (i guess he will put that drain ability instead of damage)
drain is great, it puts balance between players, weakest player can get, lets say, dst off guard (few spells would help tho ) and drain her up
but it should be a new creature, lots of players spent money on archers, and its a shame to change them, they are one of the most important creatures (mur said thats the reason ok i agree but i feel a bit frustrated spending those 43$ of free credits on tokens... on archers i sacced Lore archer, hollow warrior and a knator to get those tokens on right creatures, and 2 of those 3 got new abilities...)
also, drain on archers would make strong players stronger, the ones with drachorns at least... now nobody can outdamage drachorn auras and tokens except on pure brute force with stats, at least bloodpacts + chaos archers were worthy opponents
