Tau took over the guild to help Raven. It didn't really make it Tau's.
He tried to do what people wanted, make us stronger, more active, and doing raid's, guild nights, etc, to let people get involved in fun things.
People complained when we didn't, then people complained when we did. Few made their voices heard in the beginning, but complained vigorously later.
So, since taking over someone's guild never makes you feel totally in control, he opted to not deal with the unfolding drama and start his own guild.
There's nothing saying anyone was totally right or totally wrong, but it's a game and it's not there to be a soap opera. Better to remove from the situation than
have some kinda lingering arguments.
With respect, I don't think Raven was back seat driving him, but that doesn't mean it wouldn't feel like it regardless.
