Most of the MMOs you list OP were expected to endure the trolls, hate, flaming and unsubs as the fans here claim. Most are free to play or have slid into level of subs where many aren't sure if they're still online.
MMOs play the same because they insist on making them the same. It's a stretch to say that FFXI played the same as WoW, RIFT, or FFXIV unless you boil it down to "attacking a monster with weapons".
