I do NOT have a link to that addon. The one I used to use stopped working, and I haven't repped it yet. I assume it's still around. I'll poke around later.
Ehhhh....In my guild all dps nuke the legs both in the beginning and when they respawn. So obviously my BF uptime is low. Is that a wrong tactic? Should I be the only one that nukes the legs?
So at the start, blow them up because your strat involves a slow Garalon. But after, if a leg spawns, it sort of depends what melee is there.
Pretend it's a ret paladin. He goes buck wild on the leg while you get on the leg and cleave. He does X damage to the leg, and you do, say, 80% of X. During that time, you also deal 50% of X to the body, and the ret does maybe 10% of X to the body. The leg dies. The ret is happy he put big numbers on the board.
But this was a raid dps loss. If the ret was fully on the body, that whole X would be dealt to the body. The leg would be up a bit longer, but you are still dealing a very large chunk of your damage to the boss while you are destroying Garalon's leg. A raid using the first strat would end with bigger numbers for the ret, but Garalon would last longer. A raid using the second strategy, of making intelligent use of blade flurry, will win the FIGHT faster, even though the ret doesn't get his 2x numbers.
Now, what if the melee is another combat rogue? Well, you should BOTH be on the leg. What if it's something towards the flurry end of the spectrum, such as an arms warrior? I think he should be on the leg too. But besides the sweeping strikes guy, my feeling is, get the other melee on the boss for higher raid damage.
It can be REALLY hard to explain this to people, so you may not have the option. It's especially silly because recount won't support you to a naive raid leader, or a melee who doesn't understand what blade flurry is, or thinks it's the ripoff version of cleave or something. In general, any damage done to the leg is damage NOT being done to the boss. Because the leg dying hurts the boss, that's great, the leg should die- but the speed in which that happens is not very critical. Putting a ret or feral or enhance on the leg doesn't really help, because the damage they do to the leg is mostly damage NOT being done to the boss- but because of the target circle, their dps still looks optimal. In fact, the leg is going to die because the rogue is on it (and unlike them, is on it WITHOUT ignoring the boss), and they should focus on the actual kill target- Garalon.
