More than once. Just this week in Bunker I was nowhere even near the hit range of aoe, teleported to a safe zone in a corner with enough time before the attack and yet got killed. Lying dead under giant doll skirt isn't nice. But, well, my own potato laptop ain't helping in that regard either.
I guess scripts can be helpful in the regard of lag, cuz you know whats coming w\o seeing it. Like, my friend RajNish over here lagged like hell in Cosmos in 5.25, I believe (there and in Amarout, other duties was fine), never even saw trash mobs and bosses didn't move much on his screen. But he managed to clear the dungeon everytime he got it in roulette, not only on tank, but on healer as well. All cuz he knew what to expect and acted accordingly. And while I admire that, I also couldn't stop asking myself, what good of a dungeon is this that it could be completed blindly.
One thing that bothers me as well: trash is all the same. 3-4 autoattacks, cast or aoe, repeat. Again, the only difference is visuals. It was fun to find a mob with different abilities, that made them a priority target just to make our life easier: bees in Quarn, Hellbreaker and Neverreap, heretics turning themselves into dragons in Stone Vigil Hard and Snowcloak, that plants spawning other little plants that gives you poison debuff on explosion in Sohm Al. After that I honestly can't remember anything similar. Maybe Amarout with its bombs and sprites cutting healing outcome, but those are so easy it could be just ignored and killed with everybody else. Now imagine you coudn't heal at all if that mob was active, so you need to CC it or kill it asap, before other mobs kill the tank. I wish something like that occured more often, not millions of aoe in every new dungeon.
