The thing is, you don't have good gear yet so they're expecting too much from you. Every time I run AK, I quickly pick up and tank golems and the 2 DPS burn it down quickly; no matter how good their gear is. If they were smart, they would of recognized that their strategy wasn't working and adapted. It's not like this boss has some kind of time limit, either.
Another boss in AK this can apply to is Demon Wall. While it's possible to kill it before the gnats spawn with great gear, if I clearly see that we're nowhere close to winning after the second Repel, I'll tell them to kill them since otherwise the fight will likely be too chaotic. It's pointless to keep trying a particular strat if people lack the gear for it.
