As far as access to different gear, after gaining enough honor, which is maybe a few fights, you can obtain the guard costume, which gives you 20% extra damage in PvP. This may sound nice, but it doesn't apply to PvM and quite frankly, you'll want to use the equipment slot where the guard insignia goes for an emblem, which actually does affect PvM.
That being said, I'm not sure what type of PvP limitations there are on the Asian server.
Either way, I'd still say try the game out and see if it's your thing, but just know that PvP, unfortunately, is not a big part of the game right now. Having played the game on and off for years, I can say that you will run into the occasional PvP tournament hosted by a guild or group of people, but those are far and few between, and understandably so. This is mainly because they're so difficult to organize and maintain.
If you have any other questions let me know.
