Starting out, advice needed

[Grixxitt]

So I started out again, my old account has some characters in their teens but I lost the password so I just decided to reroll.

Now here's my conundrum: I want to develop a Troll Shadowknight but it's a bit tough with the -68% XP hit being a tank with no money and poor gear.

Should I just play another character that I can develop quickly and use that one to bankroll my budding Troll? Or just tough it out knowing I'll never get decent gear until endgame and everyone I meet will outlevel me on a weekly basis?

Also, what's the best class for rapid leveling and good farming solo/group? Druid? Necro? Something else?

thanks in advance
