Since trying it a few weeks ago, i log into panda beta every now and then.. while i think pandaria is gorgeous.. there's a feeling of 'hell no' in my gut, from having played for 6 years and finally moving on after being significantly disappointed in cata.
Its just more of the same wow. After playing (and loving) the endgame for the first time in wrath (im casual) i really can't imagine why the hell anyone should be asked to do the same thing again every 2 years.. and fall for it..
Rift is wow gameplay, but does -everything- better. So i'll stay here for my wow gameplay until its bested.. which will be a very tough call.
p.s. If anyone here things guild wars 2 looks better than rift.. please link some screenshots, or at least describe what i can do in the beta this weekend to see it. I really want to see evidence of better detail/design in gw2 than rift..
