Who uses a gaming mice, a gaming micepad and/ or a gaming keyboard?
My thoughts:
I think you don't really need a (good) mice which you can change dpi because swbf2 is mostly about mines, dets and thermal detonators (and you definitely wouldn't need a gaming mice when you play as a jedi... except maybe lightsaber throw but meh). I have no clue whether the new star wars battlefield game will be the same as swbf2 (with this I mean that the game is mostly about explosives) but I sure hope it is.
Maybe you might wanna have a gaming mice if you wanna aim accurate with a sniper rifle or if you play as a stormtrooper but it isn't necessary. There are also units where you absolutely won't need a gaming mice like the bothan spy and the dark trooper class (except maybe your pistol but meh... we all use dat naughty darkie glitch).
For me...
I always played swbf2 with some cheap mice on a piece of cardboard. In august 2013 I started cod (bo2) and recently I bought a razer death adder. I still have no proper mice pad tho except the razer sphex but it's too small for me. Now in swbf2 I play with a 900 dpi and a 25 in-game mouse sensitivity. I always played with my wrist but am eager to learn with my elbow.
