First GL while raiding, total bitch, did nothing for the guild and was a shit player.
GL briefly at the start of Ulduar, nice guy, didn't want hassle tho and was strict about trade chat.
GL through most of Ulduar, ToC, and then start of ICC normal, nice guy but a bit of a sop, wanted to keep everyone happy at all times and made a few bad decisions because of it.
GL briefly through latter half of ICC normal and most of ICC hc, real driver, took no shit and ran things like a boss, shame the players he has to lead are mostly shit.
Current GL, seems alright and keeps people in line mostly, doesn't mind when we run rampant in trade because most of the time we get the job done when raiding.
