Not a fan of the heist change. I think every league mechanic should have some sort of barrier to entry or 'opportunity cost'.
Betrayal has intel. Delve has 400 useless levels of depth. People who can't be bothered to run the green contracts and unlock/level their rogues can sit that league out.
As many have said; assigning rogues to a revealed BP would be an actual QoL change. Or NOT have duplicate rewards in the curio displays.... or rewards that shouldn't even be in a high level blueprint like old winged scarabs which no longer carry the same value they once did... or orbs of binding.
Or maybe some kind of quick exit button (provided the alarm hasn't triggered, obviously) that saves you from backtracking out when someone whispers for a trade?
Do the devs even play this game?
