Should i stop evolving my true profane?

Hello, so i am a lv45 blade master with true profane level 10. I have the merry potter recipe and roughly 50gold. I want to ask should i use the moonwater transformation stone on my true profane to upgrade to true siren lv10 before march 2nd or should i just stop upgrading it and make the new class warlock get it to 45 and maximize its gear. But i am afraid that if i upgrade the warlock gear after march 2nd, i wil fall behind in making money and the cost will be greater than upgrading my BM gears. But i have the merry potter recipe, so i should just milk money from the BM only. Also is it possible that if i maximize my BM gear now, that after its max, i can max my warlock gear as well?
