few PVP armor options

In PVP, I only have access to around 5 types of armor for any given profession. How can I use the armor from the PVE campaigns? Thanks.

There is a thing called 'PvP rewards'. This means that you can use zaishen coins or tournament reward points to upgrade the looks of your weapons and armor(not to improve functionality). To do this, talk to Tolkano in any PvP outpost or guild hall. To do so, you may need to unlock some of them first. You can unlock any of the pve skins , there are even some PvP exclusive skins like the Lesser Granite Edge. PvP rewards always affect 1 single item (it kind of replaces the item), appears in red text, and (pvp weapons ) can only be tranferred to other characters via heroes only.
