Not exactly, though you are limited.
If you start from scratch in an account and want to play PvP, you can choose pre-made sets of skills. They're called stuff like Warriors Bane or Snow Blighter etc etc... basically limiting you severely. However from there you can work your way to more skills and powerups, if you will, like runes and weapon mods. Thus letting you customize your gameplay.
It could certainly be better, but it's a good deal nicer on beginners than normal MMOs.
