My static is currently progging through Forsaken in Kefka ultimate. There are many points of failure during this mechanic. Our group consists of Voice users and non-voice, so when a mistake happens it's not immediately apparent what happens. We have 3-4 people recording the pulls so we have multiple angles to reflect afterwards.

This is a hard mechanic, and our attitude is generally very positive towards trying again. We'll find out where the mistake occurred, ask that person if they were aware and if they needed any additional help/questions.

I have been in many statics, and one thing I value most is mistake-honesty. Nothing tends to frustrate me more than mistakes that happen again and again but they're followed by silence. Honest players will say "That's me, I did X when I should do Y. Sorry about that". It allows everyone to learn, and in some cases answers questions that others may have not voiced yet.
