I hate to be the one to say it, but there are literally dozens of MMO's which do a better job of PvP than FFXIV. Why not play one of those instead? I'm serious. This game, regardless of whether it has PvP specific servers or otherwise, will never actually have the PvP to back it up. The evidence is already there in the dwindling Frontlines duty finders and the vacated Wolves Den.

The combat is simply not designed to support PvP, and never will be. With plenty of games out there offering genuine alternatives for your kill-fix, wouldn't it make more sense to PvP on them rather than requesting something which will never happen?
