I would suggest just playing what you like the best. I have my rogue main who is group-dependant and druid for when I just wanna solo (which isn't often because it bores me). I personally never minded being dependant on groups because the game is just more fun when you have some pals to go adventuring with... plus, people usually love a rogue (or 3) in group.

I actually made the druid thinking I can make some plat porting or whatever but realized I don't care an awful lot about having tons of plat or twinking alts. I leveled this rogue just fine with none of that and I still had a blast.
So it all boils down to what you want out of this game. Whatever you choose, have fun and good luck.
