Mikey was always welcome to have his character Mikeypeedizzle back. That was never an issue. We didn't really use it anyway. It was the linkshell mule, Livingthedream, that he stole. He gave it to the current leader and that is when the sacks put time and effort into gearing and doing doing missions on her. Current leader also kept some of her personal upgrade items on her as well. All those were stolen. Mikey logged on Livingthedream while we were in Omen, warped her out and proceeded to ignore our leader when she asked why he was doing this.
As for the bank... it's not a bank full of gil, it was dyna shards for our members to use. We sometimes have extra gil because people quit and leave and don't want a dyna payout, but we run contests and help people with gear with the extra.
As for Plikt, she's a diva. She rage quit in the middle of dyna because someone mentioned healing was low (it was) and she happened to be one of the whms. Our leader still paid her for the run. Then Plikt refused to come as a job we needed for a w3 run, because again, she's a diva. People in glass houses and all that.
No, we should have never put time into a mule that someone else had access to. That was a mistake but she trusted Mikey and considered him to be a a good friend. She never guessed he would do that to her. Lesson has been learned.
