Once upon a time veteran starting again, question.

A rogue is a perfectly fine choice. People are not going to have conniptions about you being poorly geared if it's your first character - generally speaking people are very happy to help newbies level up and are not snooty about it. Rogues are always welcome in groups because they are the best DPS in the game (granted, if you're poorly geared, you're not as good DPS, though still certainly worth having) and don't carry experience penalties. In the 40s and 50s, you start getting a lot of money just from stuff dropping while you're EXPing, and you'll be able to gear yourself up. Even before then, if you're desparate for some cheap gear, there are ways to farm up a couple hundred plat on your own relatively easily, even as a weak solo class like a rogue. There are lots of nice items on sale in EC for cheap.
