What exactly are you missing? You should not need to be a Linux expert to work with it, most things are actually way easier than in Windows if you ask me. You get everything the average Internet user should need right from the start and if you need more its just a simple mouse click away.
It can only become complicated when you need to run a specific Windows program, a lot of other Windows games are actually running quite easily in Wine, SWTOR is quite tricky. Linux isn't to blame here, blame publishers that only support one OS.
Got SWTOR running again btw, the new launcher only run ins a virtual desktop of 1000x615.
