Are you actually joking. GW2 is completely different =L Oooo I know let's chuck out the trinity for a start, won't make it any different at all will it? Mon dieu
I can deal with it being a GW2 "clone", it does sound a little different. I just HATE those graphics =L I can deal with them if that's the best we get but I want something grittier =p
It's not that different. It's different in the way that it focuses on different parts of the game, but still has similar aspects. WoW does not focus on the same things as GW2, but you do the same things in both. I'm no expert on MMORPGs, so I'm sure for those who have played hundreds (or thousands) of hours of MMORPGs can see the differences, but from an outsider's perspective, GW2 does not do anything different enough to make me truly interested. I would much rather play Darkfall or Mortal Online (I think thats what it's called

) that has tried a real-time combat system (even with a low budget) than GW2 which, although polished, does not make me very interested in MMOs. It's effectively the same system, done in a different (more polished and better) way. I have no problem with GW2 (I even got to level 20 or so in GW1, I quite enjoyed it for 2 months or so, but it just wasn't exciting combat).
As for the problem with clusterfu-ks in small areas like caves, you could do a sort of instancing - have groups of up to 10 people, and allow one "defending" group and one "attacking group" in each small area at one time, and then you don't have a clusterfu-k. These groups of people would also be useful for commanding large battles - have a heirachy like in real life - a group of people giving commands to the leader of each group, and the rest of the group following it.
I would -and I bet a lot of other people- pay a LOT of money for this game.
