Very recently I got into MCH and I don't consider myself good or anything and I'm looking to improve, which is why I'm opening this thread.

Yesterday we were chatting about random stuff on FC chat and then we started talking about MCHs. I ranted about how Rook Overdrive sucks and is a DPS loss and then the FC responded by laughing while claiming that it is awesome and a DPS gain if I use it correctly in the opener which caught me a little off guard tbh. I didn't ask the details of when I should use it because it seemed pretty obvious. It should be used any time during Hypercharge right? Because Rook damage isn't affected by Overheat and doesn't accumulate in Wildfire so it's not necessary to squeeze it inside Wildfire... right? I beat up the dummy multiple times with and without Rook Overdrive and every single time I did less DPS with Rook Overdrive than without Rook Overdrive. Am I missing something here? Or have I been trolled?
