Eh what the hell, I'll be nice and contribute.
Building Flourish boosts your WS damage, but at the expense of delaying your ability to Reverse Flourish(more TP = more cures and *more WS*) via the 10 second delay and consuming Finishing Moves. Also, you didn't merit Haste Samba which means you're losing out on 5% Haste, which also generates more TP.
Basically, you took the epeen option over the one that enhances both your support abilities
and your WS frequency (to a greater extent than improving your WS damage would at that).
