Ever since u14 and EDs came out, PvP has been fun and not fun for different people. Epic Destinies can make the tables turn in the favor of melees in PvP, if they are the only ones using them. Sadly they do not and all casters seem to do now (at least on Thelanis) is spam all of their ED stuff and will pretty much own the entire PvP w.out much difficulty.
I Believe that Public PvP should have things like EDs and the such turned OFF in placed like the Wayward Lobster, and the Phoenix Tavern. However, when you join private PvP matches they should be enabled and usable. Also, i think that Turbine should put a little more effort into improving the PvP system, and start putting more effort into the system that other games use. Where you talk to the NPC, and they hook you up with a group of people similar to your class. DDO has this system, but nobody uses it. Just keep this stuff in mind Turbine, might attract more players if there was a better PvP system.
