Our guild uses LC.
Every single Neltharion’s Tear that’s dropped to date has been prio’d to Warlocks (we’ve seen 3).
Warlocks were given prio on Bracers of Arcane Accuracy too.
The first band of forced concentration went to a mage, the 2nd went to a warlock.
We’ve seen (0) staff of Shadowflame, and (0) Claw of Chromagg. The first (2) Mish were prio’d to (2) mages. The other (2) mages (as we have 4) were prio’d their 8 piece Netherwind first.
The (2) mages who were prio’d Mish have Mageblades ; the (2) mages who have 8 piece Netherwind do not, but they will be prio’d Staff of the Shadowflame when it drops. I’ll also plan on passing Band of Forced to them (the 2 Netherwind mages) when it drops again.
Just about every guild has cliques. The LC isn’t very smart if they’re predicating all loot distribution decisions around what’s ideal for ‘the clique’ in the short term. AQ40 and Naxx aren’t even out yet.
Generally, you want to reward performance and consistent attendance with loot, but often times it’s prudent to spread out the drops in general to quell any potential drama and keep the raid team relatively happy. (1) person having Staff of Shadowflame or a Neltharion’s tear over another isn’t generally going to be the ‘make of break’ for a guild attempting a boss.
Twin Emperors can be downed if none of your Warlocks have Neltharion’s Tear. That said, everybody knows Warlocks are hit starved and when the raid doesn’t prio +hit items to Warlocks, it hurts the raids overall DPS. Not only does individual Warlock DPS suffer, but the raids aggregate DPS suffers on fights like Twin Emperors.
Giving (1) person Staff of Shadowflame, Bracers of Arcane Accuracy, Band of Forced, and Neltharion’s Tear towards the start of a raid cycle basically communicates to the rest of your raid team that you don’t value them.
Unless you are seeing multiples of those items drop, its pretty unreal.
When I searched for a new guild to join months ago, I made a point of looking for one that used LC. There are serious drawbacks for LC if you don’t have an accurate grasp of who the people in your guild actually are.
