I really don't think it's aim assist now. They have toned it down a lot from where they initially had it. I think the real issue is the damage output and low TTK. Fix that and I think you'll find the whole game experience much improved.

The idea of speed tanking as infantry is a joke.

I have used NOTHING BUT SPEED, since Closed Beta. Still efficient and deadly, those who say otherwise are honestly doing it wrong.

Same here.

Once AA was turned on.. harshly... I tried some other setups.. But still made it back to speed tanking as the most effective way to play as a Min Scout.

I dont think most people realize it, but aim assist is what makes ttk so low. The ability to hipfire with any rifle from 30-50 yards away and hit every shot without aiming is a problem. I agree, its gotten better, but it really does need another bit of improvement. If 50-60% of bullets hit while hipfiring, TTK would be fine. However, bullet magnetism causes slight errors that may result in a miss result in a hit for about 80 damage from a single rail rifle bullet, or 150 from a single CR burst. Add in aim assist automatically seeking the head for certain rifles (scrambler, combat), and you get a nasty combination.
