- Daily Missions for Exotics: Locking exotics behind random dailies that are only available while that daily is up is a bad idea. Pretty self-explanatory. Once that daily has launched once, the quest should remain active for that mission no matter when you run it.
- Legendary Marks: cap too low, everything requires marks, no guaranteed marks beyond dailies in a given day if all weekly activities are completed
- Iron Banner: This isn't specific to TTK, but IB appears to have actually gotten worse from previous events. I don't play this at all because I hate pvp grinding, but from reading comments here (and everywhere else online), this appears to be a major letdown. From poor loot chances, to lag, to grinding... Should probably "go back in the oven for a while," yesss?
