I was super anti wow until I tested it, so much stuff seemed bad but once I got in game I noticed that I kinda liked it. What sounds bad might not actually be bad.
Anyway, Eq2 was nice but it didn't really draw me in, the big zones were quite laggy at times and the quests while ok at first got almost annoying after a while. The graphics in EQ2 are ok but all female models have melon size breasts (can't configure that away!) and the human females model (very common) looked mentally retarded. Soe seriously need help with character models, personally that's a BIG turnoff for me.
I played only mage in EQ2, played until like level 15 and didn't at all feel like playing it.
WoW, graphics are better in game than on screenshots but mostly you don't really bother, the graphics does what they're supposed to, render a nice landscape that while eq2 looks better wow feels better and in the end wow wins graphics for me. Models are decent, especially compared to eq2 but nowhere close to ffxi. (damn ffxi models own)
Now, gameplay, wow gameplay is FUN, killing in a party is fast (at least at lower levels) and you can solo decently. It's not "fake" soloing like eq2 where there's too few mobs to solo efficiently but plain solo friendly but still better if you party up. It's definitelly more friendly than ffxi but where ffxi requires competence wow doesn't, so n00b at high level warning is defenitelly in place here.
As for beta downtime and lag, it's a beta I don't mind. As for not caring about feedback, most feedback is bad feedback anyway. After playing FFXI and no feedback at all it's good enough.
Me and my brother are going to get WoW, maybe not at launch but we're defenitelly going there and not to Eq2.
