That said, it's only a grind if you let it be. With no classes, you can do anything, and this bears repeating, ANYTHING you want to do. Naturally, you won't automatically be *good* at whatever else you want to do at the moment, but you can start doing it at any time with no penalty other than the time you spent on the skill. There is no way you can permanently gimp your character. You can temporarily slow progression, but you canNOT permanently break your char.
If you have any other questions, feel free to ask here, or in /u ingame
