It may, but I haven't seen much communication outside of 'gg' after the boss, even on runs where we wiped 3-4 times.

You can disable chat, it isn't really useful in the fights. I'll do this is toxicity becomes a problem.

If you know your role and the fight mechanics the UI provides a way to communicate all of the important information. For example, you can mark a target for your interrupt target, and it'll show your character icon next to the mob's hp bar along with the cooldown of your interrupt and targets can be marked with overhead icons for designating CC or priority targets.

It's still EA, so it needs more content and heroes for gameplay variety, but there's already about 1 WoW expansion pack worth of dungeons. 12 dungeons total. There are 3 capstone dungeons have 3 bosses, the rest are shorter 1 boss dungeons. The bosses are all well designed with interesting strategies and the difficulty ramps up pretty smoothly, with mobs getting more damage and health while adding new abilities to add complexity to the encounters.

It definitely scratches that WoW itch (I haven't played since Pandaria).
