WoW's not so bad. I, like many of the people in this thread and that remain on this forum, was a FFXI player who swore off WoW for years. I tried it a bit after BC came out and quite enjoyed myself for a bit, but only got to lvl30 before I went back to FFXI. I got bored with FFXI a year or two later and came back to WoW, and this time leveled all the way to 80 in WoTLK, and the endgame was what I found much more satisfying than the grind to level. Incidentally, this also made my already weary attitude towards FFXI's grind turn into a complete refusal to put up with hours of boring tedium anymore.
I think what a lot of FFXI players do is confuse tedium with difficulty, and they are far from the same thing. Yes, it's quicker to level in WoW, but that means you get to the beefy endgame sooner. It's more satisfying than guild war's near-nonexistant leveling curve but much more forgiving than FFXI's until recently, or FFXIV's post-20 curve. Yeah, it takes forever to get anything done in FFXI's endgame, but it often isn't really hard, it just takes forever. Yeah, you get gear more easily in WoW, but by the same token you don't spend weeks or months doing endgame and have very little to show for it. This helps motivate you to stay engaged. Aside from this, I've had to put up with much less drama due to the need vs greed lotting rules, it's much easier to put together a group for large scale pve stuff, the gui is great and heavily customizable, you have better methods of travel with flying mounts, and you have a legitimate sense of power after you get geared.
It's not perfect. The graphics will make you want to pull your eyes out if you're used to FFXIV, people can be quite annoying (but they are in any online game), people think gear>skill even more than FFXI, and until recently there wasn't much of a unifying storyline for the quests you were doing.
Still, despite what grouchy people on this and other MMO forums may be, WoW has controlled more than half the market singlehandedly for 6 years for a reason, and the reason isn't that the players are all "stupid sheep." Blizzard often takes the best ideas from other games and their mod community and implements them into their game. Some call it "stealing" but MMOs borrow from each other all the time. The trick, I think, is to learn the lessons from WoW and other MMOs and put an FF twist on them. And we, as a community, need to stop rejecting ideas from other MMOs simply because they're not FFXI and embrace good ideas when they show themselves. I think Yoshi-P understands this concept, but he may be swayed by a vocal minority on this forum, and that'd be bad for the game.
