Question regarding MNK's TP on Fcob

[Wysteria]

Hello people of Eorzea!
I've been in Final Coils for about a month, and passed t10-t12
but now I'm starting to wonder how most people manage their TP on Fcob?
my TP always goes dry after 3-4 mins of fight and need BRD to fill them up but when I rolled in PUG group by using BRD, most of people don't even ask for army's paeon (ninja/dragoon never ask for it. monk just ask sometimes but like once in a whole fight while I need army's paeon twice)
about my rotation, I only apply DoT once they reach 2-3 seconds and dragonkick/twinsnake only when needed.

And my skillspeed from items are only 44 points and with 3 GL I use weaponskills once every 2.04 seconds or so
