Commenting here since I did watch some of the interview (commenting before watching most of it so it may have come up) but there seems to be more dps checks than were brought up. For example the very first MSA arena's boss is one big dps check. If the boss teleports enough times he summons to many mobs and will begin out-healing most any damage and with him being the first boss that acts as a bouncer for the whole dungeon. It helps let players know if they can or cannot do vMSA but also can just cause needless frustration.

Any idea if they are going to reevaluate dps checks in game as the meta shifts more and more to max damage and less toward everything else?

I'm just saying (aside from MSA's overall pure and unending haterade toward me from drops) that these sort of things, while having their place in game, just reinforce the current damage stacking meta. There is a line here in game, those who farm end game content and those who can't really compete. The number of people between the two is slim from what i've seen and the way a lot of the systems are designed support this.
