Explanation about level 80 items
Every level 80 exotic set shares the same stats, but got different looks. PvE and WvW shares same items (meaning, if you join WvW you don’t have to change your items*). Whemn you join sPvP you got your items replaced and get different ones, only for the sPvP
The exotics share the same total value of stats, but which stats are on a given piece depends where you look. The stats you want may only be on a karma vendor in Orr, or they may only be crafted. So figure out what stats you want first, then start the search for where you can get it.
Dulfy has a good site listing the endgame vendors. May want to check there.
It’s pretty hard to find the specific source. For example, I’m searching for the heavy, vit,tho,pow set. Any idea where to get that one?
