Can't say I find much originality in RUN. It's basically a GS DRK with tanking ability and RDM buff spells. It's fun to play but it just feels like a mash-up rather than a unique class. GEO is pretty interesting and really feels like the FFXI equivalent to WoWs Shaman. I love Aldouin as a setting, but haven't really gotten into the Rieves or Skirmish yet. I applaud SE for trying new things but there's such a polyglot of unused and/or broken systems I wish they'd focus on things people enjoy instead of trying to reinvent the wheel every expansion/major update. When was the last time anyone played Brenner? Off the top of my head we have Expeditionary Force, Garrison, BCNM, KSNM, Gods, Kings, Dynamis cities, Dynamis out lands, Dynamis Dreamlands, ENMs, Assault, Salvage, Nyzul, NNI, Einherjar, Limbus, Sea Gods, ZNMs, Beseiged, Voidwatch, Abyssea, Campaign, Campaign Ops, Legion, Fields of Valor, Grounds of Valor, Clamming, Synergy, Chocobo Digging, Pankration, Chocobo Raising, Chocobo Racing, Moblin Maze Mongers, Rieves, Skirmish, and I'm sure I've missed a couple more. I wish they'd move away from game concept du jour and focus more on some core systems rather than this constant rebranding and reinvention.

In what way was X-2 less then infinitely more interesting gameplay wise than X? X had some strategy, but it was controlled, no sort of threat while you considered how to approach a fight. X-2 not only kept you thinking, but also gave you options to prevent (or in most cases delay) enemies attacks and commands. Compared to X, X-2s level of gameplay was like nes to n64.
