No criticism for how you handled anything in there, as i cant say if i would have done things differently. Thats a slow dungeon, but still a LONG time to spend there. If you start on edge because you dont like the instance, then it takes extra forever because of someone elses playstyle, then at the end they criticize you for the one questionable thing you did... yeah, i would have been a raging ball of fury at that point and i can not say i would have stayed quiet.
But one point i did want to make. You were wrong about limits. Its only in alliance raids that engaging the next boss causes the bar to reset. Of course, they were being dumb too. You dont use a ranged/caster limit to pull a dungeon boss(though this IS a legit strategy for an alliance boss since the limit-pull means the old bar is used up before the fight-start resets it). If you have a ranged/caster, then they should use their limit to burn down one of the trash pulls on the way TO the dungeon boss. If no ranged/caster, then a melee should typically limit the 2nd boss, as fighting the final boss will be enough to give you one bar to use on the final boss and the 2 bar limit is never needed. Of course all of that limit-theory assumes a normal-ish dungeon, and Maws does just kinda suck.
