Mostly shit like you describe. He was an old member of the clan that went to HC early in my time. He had a short stint of activity as HC, but had to deal with the Rad schism because of a dumb decision to promote Demon over Rad despite Rad having been a HC/Warlord since I joined. Generally, he would come to the first 1-2 hours of a fight, then leave through most of his time due to timezones/work/uni. However, he would then come on at the end of fights or the next day and backseat QB our decisions. Then, like you describe would take the credit for good things/wins and then tell members 'if I was there that would never happen' for decisions that ended up bad.
When my time came, Shaid, Magic, and I were the day to day leaders who actually were interacting and observing fights, he over-ruled quite a few promotion decisions. Ultimately, I got kicked for calling him out on going back on a promise he made a long time ago not to rerank a certain person because they had caused issues previously, and he KB'ed me from TS and the clan.
I didn't dislike him as a clanmate, but he was a back-stabber/secretive official who constantly put one face to members and his shitty side to other officials mainly when he no longer needed them. Ironically enough I had an Australian prof in Grad school who was the same way.
