Hey guys, I have a question regarding A7S.

When we skip the second set of cages before the first ball phase, my Blood for Blood comes back about 10~ seconds before the third set's bomb spawns.
Right now I am saving the Blood for Blood until the bomb spawns so that I know if there will be the melee cage or not. If there will be, I save it for the cage dps check, otherwise I use it. But in this case the Blood for Blood is a bit wasted since the boss will fly away when I still have it up with around 10 seconds left.

So the question is: can a Dragoon reliably kill the add in the melee cage without using Blood for Blood (and possibly without Internal Release as well) and just with oGCDs such as Jump and Leg Sweep, or is it too risky if I happen to have bad RNG such as no crits?
I am iLvl 240 with 240 weapon, 946 crit, 497 det, 786 skill speed.
