The first boss in AK is hard because it sort of assumes your healer will occasionally remember to cure the snare (so you can dodge AEs) and that your tank is supposed to pick up golems (DPS who aren't overgeared for AK can't tank golems very easily). Usually you'll get none of the above and it's actually pretty challenging. Demon Wall and Anantaboga are pretty much self-contained fights where everyone just does their own things so you don't have to worry about getting killed because someone else isn't paying attention. Even the purple orb, it's usually pretty obvious if someone's going to deposit in the wrong place so you should be able to get out of the way.
