WoW is at a delicate point where there are several F2P games that have overtaken it in visuals (you can only tweak the 2004 engine so much) and can even compare to it in size and content. Also, PvP is a complete mess and there are plenty of cheaper/free MMO's that provide a more fun and balanced experience.
So the only thing you're paying for really is the dragon-slaying, and that's if you have the time to raid. Oh and I suppose you're also paying for the unrivalled customer service. But that's about it really.
Asking $25 per month for an experience that $5-15 per month (or even free) games can offer is...well, I don't see it lasting too long. A drop to $20 or even $15 has to happen soon.
There's also a problem with the whole "Blizzard's next MMO" thing. If Blizzard releases an actual MMORPG (leveling, pvp/pve, etc) then the WoW subscriptions will take a DIVE. WoW would literally plummet. Give me one good reason anyone would stick with WoW if another epic MMO is released by none other than Blizzard? So chances are Blizzard will milk WoW for years to come.
Plot-wise, we've defeated some Old Gods, Kil'Jaeden, more Old Gods, Arthas and consider Deathwing defeated too in a few months - Cataclysm ends. What then? The only answer is Sargeras himself, the very tip of the antagonist food chain. So that's (god forbid) another potential expansion. I mean you can't consider WoW finished until Sargeras is finally erased (or turned good) right? True, it's a bit silly if the Titans ask a bunch of mortals from Azeroth to give them a hand against The Enemy of All Life and The Destroyer of Worlds...but if there's going to be another expansion, that'd be the ideal situation Edited by Tippy - 8/11/11 at 11:06pm
