To be perfectly honest, I use a hybrid setup myself. When I first started, I used a controller (played from the living room couch for a bit early on), then I moved on to the TFlightX, and gradually started buying better stuff. My current setup consists of CH Pro pedals for fwd/rev thrust, a t1600m for vert/lat thrust and roll, and mouse for pitch/yaw. I have the stick set to pitch/yaw on the alternate config, so a button push gives me an easy transition to SC control. Switching hands for control was the hardest thing to get used to.
Sometimes I just use the kb&m if I'm being lazy or am not at home, but I'd rather not.
So I get your point.
Algomatic uses 2 sticks, so he clearly sees your side of the argument.
But the fact remains that most of the best PvPers use kb/m setups.
The most common complaint from kb/m users is that relative mouse control isn't so great for SC.
Which isn't great, but is easily worked around by assigning keys for pitch. Not much of a complaint as far as such things go.
The most common complaint from HOTAS users?
Landing is hard.
I might be making that one up... (the thing about it being the most common complaint anyway) but it sure seems like Ive seen it a lot.
