Doing Ops with PUGs is futile unless everyone uses voicechat; Ventrillo, Teamspeak, Dolby, Mumble or something like that. This game should have built-in-voice comm. Even that pos DDO has built-in voice.
Totally agree. I'm sure there are exceptions, but I haven't met a competent PvE'er who doesn't use voice chat, and I do at least 2 or 3 PUG raids a week. To the OP, the fact no one was either willing or able to get on some kind of voice chat should have been a deal breaker from the very beginning.
If you want to raid with PUGs, then please download the Ventrilo, Mumble, and Teamspeak voice clients. They're free. It's almost certain that someone in the PUG will be part of a guild that has a server with one of those.
