From the github:
"Greater drums currently give tinnitus but normal drums of speed don’t appear to trigger the debuff "
"I’ve been testing this on beta and it seems ridiculously broken.
Apart from the fact that with 4 drummers in a group you can maintain 100% uptime, unlike many (all?) other speed increases, the speed increase on drums stacks (multiplicatively) with others.
Aspect of the Pack + Drums of Speed = 150% movespeed, with Drums giving 19.5% instead of 15%.
Swiftness of Zanza + Drums of Speed = 138% movespeed, with Drums giving 18% instead of 15%.
Boots enchants + Drums of Speed = 124% movespeed, with Drums giving 16% instead of 15%.
This will be “mandatory” for speedrunning raids in particular and it seems super degenerate and unfun. It’s also directly counter to Blizzard’s previous changes to drums, which were intended to make them be or at least feel less “mandatory”.
It can’t be intended that the existing Tinnitus debuff caused by lesser drums in TBC gets removed for WotLK, right?
Really really hope this gets fixed before launch and we don’t see 20 leatherworkers getting every world first."
