PvP vs RP

i know you can make either straight off the bat and the manual went into it briefly, but if you plan on eventually pvping, should you still play through the game roleplaying first? like start from lvl 1? what benefits do you gain from this again as opposed to jumping right in at lvl 20 to pvp?

In Ch1 you gain alot of skills through quests, meaning you dont have to waste faction unlocking them.

In Ch2 - There arent "skill quests" like that - so the "advantage" is unlocking the skills through money very quickly, and not having to waste faction that way, beings that they give you a skill trainer with all the skills right as you leave the "tutoral" island.

ohh i see...if i made a pvp character, id have to pvp to gain faction then spend faction learning skills, etc? but if i did RP i could get the skills via quests and gold...mm makes sense, thx
