I don't really have much in the way ideas for it, but after watching so many videos and talking to friends, Frames like Ember and Vauban need to be buffed, they've just been nerfed by either direct interaction ( ember's WoF) or indirect (wisp being added makes Vauban's 1 useless).
I remember when Ember used to be able to CC enemies in higher levels and that was "almost" all she could do since she no longer had damage reduction and Her powers didn't do % damage or increase, she could however buff guns, but I'm sure many players will recall when Ember got nerfed again with her WoF doing "more damage at lower range", which was 100% a nerf, there is No way it is a buff.
Then there's Vauban, That is all.
I know it's a stupid "want", but I would like all frames to be Usable at higher level gameplay with unique roles, so Ember she is fine if she isn't a CC frame with firequake, but at LEAST give her more damage, and if they want Vauban to be CC, let his CC bypass nullifiers, I know that's a really "bad" idea, but isn't Vauban the "anti-corpus" frame thematically? Shouldn't he be able to counter the corpus extremely easy but have the other factions be a bit harder? Maybe let me him CC anything as long as they have a shield to "malfunction" or something.
