Except as I explained, PvP and PvE players typically want different stats from their gear, so what's best for PvE isn't necessarily best for PvP and vice versa. In WoW, you can use any gear anywhere- but the latest raid gear set for each class doesn't beat the latest PvP reward set- It is common, however, for people struggling to progress in PvE to obtain a decent PvP set, which will help them get their foot in the door. At the same time, The best PvE set is geared towards the needs of the PvE player- so it may help get your foot in the door in PvP, but becaue the needs of a PvP player are different, it is not an end-all gear solution.Then you are like I am going to step in to arenas and faceroll a bunch of PvP only players because of my superior PvE gear.
In other words, PvP in WoW often served a similar role as the Skirmish event in XIV 1.0- not the best stuff, but it can give you that extra push you need to advance to better stuff.
PvP and PvE gear do not have to be seperated, and PvP and PvE should not have seperate levels or anything like that. It destroys the whole point of PvP to many people (seeing how you stack up with all the best stuff you've gotten so far, or using PvP as a testing ground to see how certain things work) The only separation that is needed is interaction- Keeping PvP combatants away from PvE combatants e.g. not letting PvPers ruin a PvE'r's fun or vice versa.
While seperation in all aspects does work from a technical standpoint, it devalues both systems - Fans of PvP feel like they're restricted to only playing PvP becaues it takes time away from PvE without giving them anything they can take out of it, and fans of PvE are left with no incentive to participate. This was the fate of Ballista in FFXI. It was inherently unrewarding, so only a handful of hardcore players kept playing it after the initial newness wore off.
PvP will only just begin to go into testing in the final phase of the beta- so it's unlikely that PvP is going to be immediately available at launch.I agree, I should make this very clear im not a PVP ONLY person i love PVE and the story line, i just happen to also like to pvp as well, If they need to delay the relaese of PVP so they make sure PVE is done right im all for that!
I honestly have every confidence that YoshiP and the team are handling this with the utmost care.
