So, another request from me!
As the distance to an enemy is highly variable, so is the need for a size in FOV. Long range sniping with deagle requires very little FOV, in close quarters that FOV can work against you.
Again, sorry for being late to the party if this is already on the TODO, but thought i'd just share anyways. Play a lot nowadays, and ideas tend to pop into my head all the time :)
