imo thats too long to get into a trick attack. Thats over 11 GCDs before trick goes up. You ideally want to get get trick up between 4-6 GCDs, as that seems to line up with other jobs the best. Next you want to get as much potency in that window.

With what I posted you get TA up quickly and get all of your oGCDs on cooldown as soon as possible. It also stacks a lot of the high potency moves underneath trick attack.
