Disagree on not being able to transfer skills from regular AAA FPS games.
Personally I found my twitch shooting skills from CoD and Halo (I hail from the land of consoles) apply to engineering, and some jumping skills from Halo also transferred.
Grenade throwing/any guns with ballistic arcs transferred pretty well to the projectile weapons of GoIO (although the duration of travel is much longer).
I was a terrible sniper in Battlefield, but since Battlefield has projectile drop and velocity, compensation skills carried over.
Many players do say that Tribes: Ascend's projectile velocity inheritance is pretty good for learning the same concept in GoIO.
General reflexes are certainly useful in GoIO for dodging rams, hydro etc, just less so than FPSs.
In terms of piloting, giving arcs to gunners is not unknown in FPS territory. In Halo, learning to drive the Warthog properly in order to give the turret gunner good constant arcs without also exposing your Warthog to enemy fire for too long is pretty tough, since everyone has the ability to quickly destroy your vehicle.
You can certainly solo (as in, you and your crew) carry your team to victory in GoIO
Edit: Forgot to add in Planetside 2, where occasionally there are exhilarating moments where your highly coordinated, communicative and severely outnumbered platoon can delay and even defeat a vastly larger uncoordinated enemy. Also there is an air vehicle called the Liberator which has a dedicated pilot, main gunner and tail gunner which requires very good communication and individual skill between its crew to function at its peak efficiency role of targeted bombing.
Really there are only 2 concepts not transferrable from your typical AAA FPS:
1) Teamwork. Most AAA FPS don't need much teamwork since individual accomplishments are influential for winning the matches. Furthermore communication is not encouraged in pub matches.
2) No gameplay unlockables, thus the game gets boring fast to players expecting to unlock new ammo, ships, tools over time etc.
