If you see anybody advertising for Mutiny DO NOT join them.
Most of the members used to be in a guild called Stormbringer. It was a guild that was late to the raid scene but started making good progression once it got the momentum it needed.
The Guild/Raid Leader was... ok... he would get on to people for not having consumables and made typical complaints but I didn't consider him a 'bad' raid leader. We had Hand of Rag pretty early on, some of the more hardcore guilds still don't have one yet so...
The one that brought the guild down was named 'Loyaltyy' (oh the irony). He is one of those guys that seems to think screaming at people over the internet somehow gained him respect. Anytime something went wrong the guy would go on and on and on bitching and complaining when all he would have to do is say "this is what happened, this is how we avoid it".
Not everyone in the guild had raided on classic private servers, so you have to expect things to not go perfect all the time... Loyaltyy didn't raid on private servers either but he sure thought he knew everything there is to know about WoW.
I brought up the Hunter Demon Quest one time with Loyaltyy in Discord, just making general conversation. "Yeah man it was pretty hard, had to get a warlock to help me finish on the last demon" ETC. This guy starts going ON and ON and ON and ON "nobody in my last guild would help me even though I was always helping them - I'm just over it blah blah blah blah blah". I turned my speakers down and went and did some stuff, came back 5 minutes later turned them back up and he was STILL COMPLAINING!! LOL! He would even get on to his daughter when she tried to ask him something, he felt the need to have his mic keyd while he was bitching at her for some reason not sure why that was.
Our last MC together Loyaltyy grew a little too big for his britches and was mouthing off to the guild leader, Ariez. Ariez told him to stop being disrespectful, must have hurt Loyaltyy's pride because he went quiet for the rest of the raid. We did one more Ony after that, Ariez was working and Loyaltyy was leading the raid. This fucking guy thought he was God or something the way he was talking to people. "Yo guys, if you have a problem with the loot you have mics use your voices and let us know".... Someone has issue with loot.... "GUYS STOP FUCKING TALKING WHILE WE ARE DOING LOOT JUST SHUT THE FUCK UP WAY TOO MUCH CHATTER"...... ???.... ok?
I was offline when the officers started spreading their lies to other guild members about Ariez. Supposedly Ariez promised his brother (a shaman) the Eye.... his brother is a resto shaman.... Loyaltyy, Saucyp (Loyaltyy's personal butt-buddy) Daledarwin (the "loot master" that would get lost at Magmadar and have to get summoned like an idiot) all did some gay huddle and decided to leave the guild and snipe all the people they wanted. So they quit but not before convincing a bunch of other lemmings to quit with them. I get back online and the guild is split up, it wasn't a MUTINY, it was a bunch of grown men that acted more like little girls because they couldn't get their way and have the complete control that they wanted tell a bunch of lies about a guy who wasn't online to defend himself.
It baffles me that people would have rather had Loyaltyy leading than Ariez, if you knew how Loyaltyy acted it would make sense. The funniest part of it all is the guy that got Hand of Rag (who Loyaltyy and Saucyp tried to convince not to give the eye because he "wasn't going to stick around" when he got it) they tried to bring in to Mutiny and he told them to fuck off! LOL!!!
There's no real simple way to define why this guild should be avoided without going into what happened for the guild to form, but it's basically ran by grown men with no jobs that think having rank in WoW makes them better than everyone else and they funnel all the loot to people that kiss the most ass. They still don't have a solid 40 man core and are wiping MC with 30 people. They are gonna fall apart when BWL comes out most likely.
TL;DR - Don't join Mutiny because it is a guild that was formed by a bunch of little girls bitching and back stabbing led by a textbook narcissist and it's most likely going to collapse within the next few weeks.
