[@liferusher]: All right, form analysis time.

1. No subclasses. Wipe that from the form. No need for it.
2. There are a bunch of chronological inconsistencies with the backstory. For example, the character is 23 and has been a shut-in for 6 years, but 'aced school [and] got a decent job'. Logically, there is a buffer window between that and the withdrawal from society, but given that the character would have to have been 17 when that happened... Yeah, things don't add up. Also, online job with what must reasonably a high school diploma at best seems sketchy and at worst feels like a complete and utter scam.
3. Oh boy. Solo clearing endgame. Where to begin...
Okay, the big problem here is that content developers for an MMO are not incentivized to make solo content aside from MAYBE story. That remains the case here; allowing players to run through an entire game on their own devolves it from an MMORPG into just an RPG, which defeats the purpose of multiplayer. Heck, many bosses these days have mechanics that require multiple party members to cooperate in order to accomplish. I doubt that'd change here.
So... Big no to that. No endgame player should be soloing endgame content meant for party play.
4. Dual wielding katanas...
Can I just give that a no based on swords? Katanas are generally able to be wielded with one or two hands, yes, but the balance on having to dual wield them is bad. You've got other swords as options, but still. If you [i]really[/i] want them, you'll have to make a case.
5. Level a tad too high. A bit lower, please.

I think that's it for now.
