lol, i never used tali once. I stick with Garrus and Wrex the whole game with my pure soldier. I have a biotic soldier too that i just started out with. So i don't know where i'm going with him.
And i played through like 8 times! I'm working on insane with my lvl 60 right now... they're not kidding. It's insane...
But the Pinnacle Station dl seems pretty interesting.
It seems to look like 2 is going to use more ammo based weapons rather then heat...

I'm going to suck, because all i do is spray with the assault rifle.
