I certainly do.
For me personally, M+ has been a great breath of fresh air for the game. I did M+ non-stop in Legion and continue to do so in BfA. I imagine Shadowlands will be equally if not more fun in M+ but I was wondering if Blizzard will ever add new affixes.
The seasonal affixes at level 10 and beyond are cool and all. I'd still like to see new ones in rotation as for 2 - 9 keys.
What would you all like to see as new affixes? How about current affixes being revamped/redone?
