I'm not joking! I play both of these games and I know people don't like their game to be criticized, but I criticized both. Ultimately I think these are the best two games on the market right now. If they'd combine the selling points of each the result would be perfection.
Take GW's excellent graphics, simple-yet-effective interface, the very customizable class system, a great skill system forcing hard to make choices with limited skill slots, missions that are simply amazing, great PvP, and the focus on small group content. You now have a foundation on which to build a great game.
Add in WoW's depth/polish factor. High level of character control/responsiveness, a much more interesting itemization system, non instanced areas to quest in, great server quality, excellent quests, engaging dungeons, deeper level of lore, and things that just make the world feel so much more "alive".
Add these two together. The core mechanics of GW + the polish of WoW. I think we'd have a monster on our hands :P
