Tells as I said are fine, witin reason. It's the issue with invites while I'm in the middle of a quest, fighting monsters that can get very irritating. I doubt you'd enjoy someone giving you an invite in the middle of a raid, would you?
I appreciate that I could put myself on anon, but the thing is, I don't have a guild. I sometimes will be off the game for long periods of time, and I didn't want to burden a guild with that. I'll do pugs sometimes though, and I'd really rather not have to go anon and switch off every time I wanna pug, then switch back on when I solo. I guess we all have our own opinions on this.
