I really like the default controls.
It feels like you have your right hand working on the majority of gun controls (aim, shoot, ironsight, reload, etc) and offensive moves like nades. And on the left hand you control movement, run, duck and cover, and melee.
So if I want to run up to someone and melee I can do that all with the left hand. And if I want to just stand there and shoot with the ironsight that's all on the right hand.
If that makes any sense.
