Hello,
in a last night 25 Naxx raid, we noticed that his Locust Swarm speed is bugged again. Earlier, it was bugged on 10 man and working on 25 man. Then they fixed it on 10 man too , now it's bugged on 25 (not sure about 10 man, haven't done it in the meantime). I noticed that they fixed Gluth and zombie heals, but somewhere and somehow, they bugged Anub again. It's still manageable with 2 tanks and potions of swiftness and swapping them for 2 locust swarms, but please fix this again.
