Double Uppercut: not so interesting?

You have a point there...
I mean,if you can't do CSP>BSB in a string-
BSB would still be good to max 2nd.

What I'm getting at is,if you leave DU at one,it could serve as a link between CSP,and BSB,since it's easier to come out with a DU right after CSP.

It'd sorta work like this: CSP(pretty much leaving the mob half dead),Do a forward-jump DU(gets the mob behind you),then mop up the remaining monsters with a BSB.

Though it would work[in theory],it would require you to be able to hit about 4 buttons in a fluent string.

But by the time you max CSB(which should be lvl48-ish),you would hardly need any compound combos to kill monsters. Most of the mobs you'd be training on by then will only require,basically,a charged CSP,and an SSK.

Also,by the time you WOULD be needing compund combos to take out monsters(around the 60's,maybe-),you'll probably have 15sp on BSB,and considering that CSP will be even STRONGER in the 60's,you'd hardly need BSB.

BSB is more of an improv. skill,when you don't have the time to wait for CSP to charge,or if you already used DU and have a mob coming at you.
