I love how everyone says FFXI was the best system, yet they aren't playing it....

It's not the system that turns player on one another, it's players lack of patience. FFXI CoP was a fine example of this because it had the same issue as FFXIV end game does. Outside of an LS or Static it was very tough for a player to progress due to the difficulty. Do you honestly think there was a difference from FFXI Diabolos wipe and Garuda EX wipe? It's still frustrating no matter how you wipe and you still have the blame game.

So in short every MMO has it's share of frustration in end game arena and FFXIV is no different.
