I hit 70 on my resto druid (Horde side) the other day. Since then, I've run SH twice and SLabs, which was with a PuG. it was the best SLabs run I've ever taken part in...there were no deaths except for me being killed by groupmates during the 2nd boss' Mind Control. This group was 4 new 70s and a 69 rogue. I hate to boast but I got lavish praise at the end.
Then yesterday I joined a PuG for Steamvaults. The first bog lord mob at the start 3-shotted the rogue who managed to pull aggro off 2 warriors. He yelled at me for not healing him. A few pulls later, tank went out of line of sight while I was catching up (I had been recharging mana) and pulled 4 mobs. By the time I caught up, I had to blow cooldowns (NS, swiftmend) to heal him and the rest of the group, then I pulled aggro and died. I left the group and got the nastiest tells I have ever seen in my life from the group members, telling me to L2P, kill myself, etc. Apparently I'm on all their "blacklists" now. I came very close to throwing my computer out a window, and it's at times like these I wished I could punch other players in RL.
Just for clarification, I'm healing in like 2/3 blues and the rest greens. Yes, I have 5 points in Subtlety so threat is reduced.
So is that my fault and I need to "lrn2play noob"? Or was it just bad luck with a PuG?
