They kinda flip flop on it. They didn't want me raiding with them because I told some undergeared people they should try getting some Tanaan Baleful loot, and so I was being too elitist. Rather than use running BRF heroic for them some loot on a raid night (this was actually suggested), I said they'd be better forming a couple of groups of 5 and running the Apexis areas, or hell, Mythic dungeons. These were people already in the guild, I was told it would be a future investment. They killed Hellfire Assault on the second or third attempt, wiped on Iron Reaver a few times then called it a night. One of the "future investments" left the guild, another stopped raiding due to uni and the third hasn't been seen for a month or more.
Ironically one of these undergeared people a month or two after this event told people they couldn't join the raid team until they got a higher ilevel. That moment of hilarious hipocrasy caused at least one person to leave the guild.
People that are "established" can reroll of new alts that are shit geared because "that new class is better synergy", than the one that's 50 item levels higher. One guy changed from priest to hunter, then a week later they denied a shaman from joining the guild, because according to the hunter (previously priest) the shaman (and thus hunter) token already had too many people fighting for it.
Yes, it makes you laugh ... a lot
In all honesty, I personally think the only reason they got Archimonde is because, compared to Blackhand, he is a lot more brute forceable. They couldn't kill Blackhand (even on normal), mechanics kept fucking them up. Archimondes mechanics diminish quite a bit if you can just output a load of damage.
