I totally agree with twisted.
GW 2 will have stuff of has already used by many mmo's and other.
But also it will have stuff in his own way.
In my eyes GW2 will never be like another clone of wow. There will still be a lot different than wow.
Wow has been succesfull in a way that's true but still I'm not gonna say its a good game. it just how they played it. easy to get into and lots of advertising made its succes.
but on the other hand there a lot of things in it that i dont like( just from reading).
For example the endgame stuff is not very much other than some pvp, raiding and doing some quest with to large parties where you get lost in the crowd.
Also like in many games fighting is nothing more than mostly pushing the buttons.
In guildwars on the other hand you also need to use some skil to make a good build.
In guildwars 2 there will be less skils but it will be more important to make up a good build to play.
In the end Guildwars is not like wow and never will be.
Also like twisted already said we musn't drag us into the war of gw vs wow.
