I completely agree that Killing hordes in the shortest amount of time selling point for Warframe.
I think tonkor/amprex meta was a much less room clear meta compared to how it is now where u can not even see the enemies before they die. I think this just comes from the evolution of the game, but I just feel like it should be more tame. I dont expect my opinion to change anything though.
Ive been playing off and on since the beginning. I know nobody is forcing me to use aoe weapons, I do play how I want, and I still enjoy the game.
I just wanted to see how others saw the meta. I really haven't seen anyone talk about it.
I can see now that its just how the game has evolved.
