More ranks on top is an idea I haven’t heard. I like that, although doesn’t upping the difficulty of the top rank just make some of the lower ranks possibly relevant in a challenge context (for those clearing old H40?)
And as for not removing maps/modifiers, and instead adding to the pool/variety, I think everyone agrees on that:
But the gunner nerf sounds good (and was much requested), and something like the pacing changes (to fix the breaking of spawns) have been asked for by folks for ages.
