As someone who used to pvp but stopped when I13 rolled around, yes these are they type of suggestions that got us into that mess, but they are extremely valid suggestions. The devs just went the worst possible route into addressing the issue as they did not seem to understand what made the pvp in the game fun.
Back on topic I support this suggestion as pvp has been in need of some re-balancing as many sets, and even whole ATs just are, never have been viable. Which is a pretty big turn off for those looking to get into pvp when they find out their main will just get steamrolled no matter what they do for making the wrong choice at character creation. I only ever got into PVP because I was running Ice/Dev back in the day and that happened to be decent in pvp zones. If I was running AR or something else that wasn't really good at the time, I probably would have never touched it or even have been against its inclusion like a lot of people were.
PS: PvP, like other have said, runs on a completely different system then PvE, power can have different property's there while not effecting anything in PvE, its been like that since I13. So changes in PvP wont effect anything else.
