I've been playing EQ1 for the last month... Haven't played WoW regularly since Jan of this year... I got back into WoW for like 30seconds and then the /follow nerf happened, and made me quit all over again.
EQ Next looks pretty sweet. I'm having tons of fun with Nostalgia overload in EQ playing 6 toons. EQ Next looks like a game changer, but then again if they make it too fisherprice like, it might be lame. I still miss the hardcore EQ pre-kunark days. EQ1 has had a lot of improvements over the years, and Sony has seemed to make it more casual. The MERCS are a great idea in my opinion :P
