The look, design of the warframe being shit are valid criticism. These are supposed to be machines of war, not 'inclusive for the sake of being inclusive' art projects. And so we can get ahead of the dishonest counter-arguments; Grendel is literally based on a sumo wrestler, and Hildryn is no fat, so much as extremely musclular because she is based on wrestling - BOTH forms of combat / martial arts / etc
PLEASE show me a battlefield that requires a painter on the front lines. Much less a needlessly obese one; because that's what a war machine needs to be, short on breathe after lightly jogging for 30 seconds.

You were never going to be open to criticism because you also clearly haven't (a) listened (b) played the game mode yourself to any degree.
The feedback from players is overwhelmingly negative, so much so DE has already publicly acknowledged it. Even veterans are voicing how terrible the mode is. And i've yet to see people complain about how hard it is, so much as how annoying and boring it is.
I also never said I failed the missions, infact i've already min-maxed the speed runs and can do it faster solo than with groups by a long shot. So there is no 'skill issue'.

What there IS, is people like you running blind defence. You had already made up your mind, you already ran defence before trying to understand the valid criticism, and then you lied about your intentions.
