When it comes to pro gaming, your choice of controller is as important as the loadout on your soldier. Your controller is a weapon in itself, but not all controllers are created equal. What works best for me, might not work best for you. So long as you are using what works best in your hands, the sky's the limit.
I have been going back and forth between the Nacon Revolution and the Razor Raiju, for about 40 days now. Pushing myself to the limits in games like Call of Duty, Battlefield, Overwatch and Titanfall, to name a few. It has been fun and learning experience so far.
