good vid. I'm trying w my lvl 20 char and get demolished on 2 star, everyone is sayin the lower rank your character the easier it is but i see nodiff between my lvl 20 and my lvl 7 in terms of bot difficulty.
The lower bots don't have all of the abilities that the higher bots have. Like reviving themselves, throwing lazarus grenades at a pile of their teammates, cortex bombing, downed-firing at you, planting gatling turrents everywhere, double mining your favorite routes, etc etc etc..
Also, the lower AI really are a lot easier to just run over or sneak around.
I know some of the tips I made in the video seem irrational, unimportant, irrelevant, stupid, or almost enough like something you've already tried to not matter; but I strongly recommend that you give them serious consideration.
Same thing with the unmentioned tips you can garner from the video..... Like my body-type + usage of battle-hardened, my weapons choice + usage of ADVANCED damage buffing, how I aggressively attack enemy a key points while seemingly ignoring enemies pointing their weapons at me at other key points. All of that really plays into it, believe it or not.
I really wish I could talk a whole lot faster, so that I could have given a much more detailed commentary as opposed to the laid back one I went with.....
