I will admit without shame that I usually never drop the CS on A1NM except for huge emergency
The damage are so ridiculously low (compare to the savage) that I expect my partner to solo it easely XP
(But i always check his stuff... To know if he has enough healing output to do it)

The best A1NM i did
Was solo heal (me as AST) and solo tank (war) and a pack of 6 blood-craving DPS
So fun but sometime so hard XD
