Final fantasy 14 is considered one of the best mmorpgs out there and it certainly has one of the best & nicest communities. It has a lengthy free trial (like the first 60 levels) before you have to pay (I think $15 a month & paying for the expansions which you can usually get on sale for cheap). It has several jobs/classes like this and everyone says the main story is really compelling. Plus, there are lots of guilds, raids, and community events.
As a former ragnarok online player, I think this is based on it, because I can relate so much to the manners of PVP and Guild wars. It keeps reminding me of Rag mechanics and chibi art. I feel like I've met all the people on this guild ( ̄∇ ̄") the only thing Rag has is a uniform for classes, and it's not as customizable. At least it wasn't back in the day.
SERIOUS INQUIRY GUYS:
PLS RECOMMEND GAMES LIKE THIS WHERE WE HAVE TO TEAM UP WITH REAL PPL AND HAVE A SPECIFIC CLASS/JOB. PLSSSS
