GW2 gameplay is nothing like WoW or EQ2 gameplay though.
I played GW2 for a while and other than the fact that weapons determine what skills you have, it's WoW/EQ/SW/countless others with better graphics. It's a third person game that relies heavily on cooldowns with your skills auto targeting everything. I played WoW and GW2 exactly the same, you just run up to an enemy and start spamming your auto-target cooldowns.
I don't think it's dated, it's what is popular so it's what people play and devs make. That's just the combat. FF14 actually has a good amount of differences from WoW.
I think ESO is unique which makes it interesting, but I also think it has a really big chance of flopping.
You are right in that it's what the masses like, I'm just not one of the masses. I don't like modern military shooters like BF/CoD, yet they sell like nuts.
I've been playing "stand still, throw out auto-target cooldowns while enemy beats on me" MMO's since 1999, it feels extremely outdated to me at this point.
