Some thing im not to sure about cause im new

When it goes to the role play thing and the PVP thing what should i pic whats the diffence it says you can still pvp as role player?

Whats the diffrences and what should i pick . Also how many Charaters can we make? I if its only one i dont want to mess up

Role play= (unlike role playing actually should be) just starting from level 1 and then make your way to lvl 20 and get into a guild and all, you're still able to PvP with an RP char.
PvP char= you can only do PvP, you start with a lvl 20 char, but you can't leave the arena areas to do PvE.

I wanta pvp . But what would you choose?

I'm going to RP, i'll do PvP when i feel up to it :P I don't have the game yet however.

How many characters can we have?

4 per account i believe.

You're going to want to have an RP account to unlock skills for PVP. A PVP account starts at lvl 20 and you can choose from pre-made builds, however, to make a custom build you will need to unlock the skills you want to use.

Are you aware that the only choices available to a PvP only character are a few premade characters with select skills and the skills, armor and runes unlocked by your PvE character. You will need to PvE enough to unlock the stuff (skills,armor,runes,weapons) you want to use. The default PvP stuff is pretty generic and doesn't give you a chance at a really custom build.
