I haven't played with any of you guys, or in any kind of 'organized' games yet, and I'm finding the game extremely enjoyable.
You don't need organized games/lots of friends to enjoy, though I'm sure it helps, as it always does in similar games. Once you get the hang of the mechanics of each class, the game becomes a blast. At first I was a little put off by hit detection and not understanding who was hitting me, but after a couple hours even the more chaotic fights are pretty readable, especially if you distance yourself and just work your way through the edges of the fights, rather than running right into the middle.
So far I've only come across two things that have bothered, but certainly not game-breaking. The first of course is connection issues. Its mostly just been 'Unable to connect to this host' and after 2 or 3 tries I get into a game. Last night however, I could not connect to anything. =\
The other thing I hate, is bombs. The big ones are just irritating as their radius seems massive. The little ones are also annoying as people just spam them everywhere, and can kite you like no one's business.
Otherwise the game is great, and I'll definitely get in on some gaf games. For those feeling uncertain about the game... give it a couple hours, and once things start clicking, and you learn how to properly play each class, it becomes all kinds of awesome.
