Honestly there have been so many idea posts on the forums... If devs wanted me to, I wouldn't mind consolidating the ideas based on what they want to accomplish with the warframes.
But it would be nice if these frames got some more tweaks than they've initially gotten. Like:
Titania's floaties go all over the place, which makes them consistently-inconsistent (and pointless to use... it's more of a pain to use the floaty cc, than to simply kill the enemies)
