One of the things that worries me the most about WoW is all the people claiming "You can solo! You can actually solo, you don't need to sit around for hours to find a party"
Now, maybe it's just me, but I'm not paying money every month to play a game by myself. I LIKE parties. I much prefer the social atmosphere in a party, talking and killing in a relaxed manner then soloing monsters to level up. I don't like the powerlevelling parties, but rather the more relaxed parties who don't care if they aren't getting 1000000000 xp/hour.
The problem I see with WoW, everyone is saying how great soloing is, and that it's even better than parties sometimes. I can imagine a vast majority of people would be soloing. Which leaves a bit of a problem.
If it can take an hour or two in FFXI to find a party, when everyone (Except Ninja, Red mages, Beastmasters, or low/high level Summoners) HAS to party, how long will it take me to find a party in WoW? Hours at least, one every few days at worst.
That's a problem with making soloing viable, for those of us (Like me) who would RATHER party, we won't be able to, because everyone is out soloing since it is the fastest experience. But what's really the point of having all that great gear and best levels, if your the only one ever benefiting from it? Why not just play Disgaea or something if you want level 9528 by yourself.
