I really like the game as well. Playing more and more, the powers and teams seem really fun.
I wish the maps were more varied. Some have identical layouts and some just have a sort of re skinning.
The random environment conditions are cool though.
Would love to see more open places "volume wise" so that the teams could really exercise their team play better. Also would like to see special areas that only certain WARFRAMES could open. Such as Excalibur being able to jump extremely high, reaching a vent that leads him to a special unlock console to open other secret areas for extra loots. As well as destructible walls that only Rhino or another hard hitting WARFRAME could smash open.
I just want more things that make having different powers more significant. Right now it feels mainly like tank and spank. Either way with time I am sure this game will evolve and grow. Already, even with bugs and glitches and its lack of depth, having a good bit of fun.
