So obviously, as title states im new here. I was looking for some advice on what to make for a pve toon for farming to get me started with cash/gear. I keep reading necro is good, but then there is that stigma attached that they are terrible people and there is to many, so I dont know if i should make one lol.

My RvR toon I was thinking between arms/merc or a reaver

Yes, people are starting to HATE necromancers on Albion. That being said, if you want a class that can easily solo and farm it's not a bad choice.

A Matter Cabalist is also a good, cheap option.

Friar is supposed to be pretty good as well for farming, and at least you might get some dragon raid invites for Heat Resist too. Probably requires a little more effort/time to make it awesome (some realm ranks into Dodger for example) but I think you can pretty non-stop.
