Try single-class and go whole games without changing.
Or try a "jack of all trades" build with abilities from every class.
I'm not saying you haven't tested all the different individual options, just suggesting that you probably missed a few different possible combinations.
Have you played for a while as a Heavy Operative? Have you played as Medic with every body type? Have you tried taking a pair of SMGs when you're a Heavy? Have you tried being a Light Soldier using an unscoped Drognav like it's a shotgun?
It's nice to see that you all defend and care for BRINK, but sometimes it's a wee bit silly, Oblivion
I love BRINK too, but I can't help but feel this is not the full game we were sold - anyways.. If he says he has tried everything, it's no use to find loop holes in his statement, like ''have you tried smgs on heavy?'', it's like saying ''have you tried chocolate sauce on your chocolate ice-cream with chocolate bits in it?''
I'm sorry if I come off as rude now, but.. I don't know, I'm a wee bit swayed right now :/
