Thanks, I appreciate the patience with me.
I used an archer in the beta, but will probably roll a new character for Early Access and the actual game. I liked the archer in my limited time with him (only got to like level 4 maybe), but was wondering if there's a character type anyone reccomends? I usually prefer to used ranged/magic characters, though I understand they will probably be fairly weak in the early goings.
I got the EA code to work, and it's working on PSN too, but apparently I have to download the client again? That's kinda lame.
No problem at all! I'm still relatively new to MMOs myself, and I definitely get that all the terminology can be confusing. My recommendation is to read/watch as much info as possible, you'll pick it up very quickly. Assuming you're rolling on Cactuar, joining the CAG linkshell will provide a group full of people who'll be more than happy to help you out.
If you want ranged/magic characters, your best bets are sticking with Archer or going with Thaumaturge. As for whether they're "weak" it really depends what you mean by that. They both do among the highest damage in the game, but they're not going to be able to survive much damage either, so part of playing those roles is knowing when to dial it back so you don't pull aggro (in other words, you don't want the monsters attacking you). Also keep in mind that both classes, especially in the later game, have significant party responsibilities beyond just dealing damage: For Black Mages, crowd control in the form of sleep spells is crucial. For Bards (which is the job which follows Archer) they are responsible for maintaining buff/debuff songs in addition to doing damage.
If you just want to hit things and watch them die, I'd actually recommend the Lancer, which is a melee damage dealer. From everything I've read they're a very good class for MMO beginners, since their rotation is a bit easier to master than the Pugilist.
Really though, this game allows (and encourages) you to play multiple classes, so the best advice I can give you is to eventually try them all before settling on what feels best to you.
Edit: You do NOT need to download the client again. The open beta client will work at release.
