I generally don't get pissed off as I assume all Asurans I don't personally know, or know of, to be dimwits. But this got me angry because I have a personal history with the aggravation of farming Tunga.
So I create a pug group for Itzpapalotl farming, scales reserved. We go off with 4 other people that want +2 items, including Chedeour. Start out with competition from another warrior farming scales, lose claim the first 2~3 spawns. No problem, built time in the meanwhile. We get one full set after a while and then go for another claim, which Chedeour gets.
Then we go to Itzpapalotl to spawn him. I, knowing Chedeour will probably be a flake, ask him to spawn it. After 5 minutes of waiting for a reply he finally says "i no have ki." He meant the KI dropped by Granite Borer, so the other person who claimed Tunga spawns it. Everything goes according to plan, then we get ready to spawn granite borer. He's afk somewhere while everyone else has gathered. I ask him whats up, he says *goes to look at the chat log* quote "am about to go. ran out of time-" we farmed TE, I was at 155minutes at the time, "an got dyn to run".
At least he didn't ninja lot. But in my opinion stealing the only relevant KI for Itzpapalotl is much worse than ninja lotting.
For the record I made it clear in the shout that it was indeed a "Itzpapalotl farm (6+ kills)".
He's not a real troll, but I would say he would do something like this again, so if you do pick up groups for empyrean weapons or +2 items, stay away from him.
(TL;DR: Chedeour left the party prematurely after obtaining Tunga's KI from the party's hard work.)
