I used to get so frustrated with Posi 1. I stopped leading it. I stopped joining it. I found it was one of the few TFs my baby toons could actually solo at +0. I complained a lot to my friends and they said "why worry about the rules, just run it at +0 with the team and what's the worst that could happen"
+0 seems to be the trick. Since we started that I have only had a few wipes and I lead this TF twice a week for years now. If they pull extra groups..pop purps and make jokes and laugh. I have only had wipes twice in the last two years. we never intentionally clear the stairs, we wait to see what happens.
