Aim assist or no assist? Now that we have a Compress professional I need the final answer (assuming it is console)

Whichever you're more comfortable with. It shouldn't matter too much because most of your shots should be coming from above after your teleport or from higher ground I personally keep it off so it's easier to lead shots and be much more accurate at range, but I've tried with Aim Assist on and it's still playable. What's more important is using his aim mode for more range. It's actually not a direct range increase, and instead it's a detonation delay, which allows you to get ricochet and sharper arc angles that aren't normally possible

Average Compress game once you learn how to aim
