So Ive been doing some bosses and I wanted to get some opinions

I havent quite done the math yet BUT I think there are times you may want to spend mana without enough mana to do the entire combo. Let me elaborate

Ive found that quite often your embolden+manafication are like 10-15 seconds away from coming off CD right when youre sitting at 30 or so mana. So what do we do in this situation? Build up to 80 and hold the CD's to use it them OR (and this is what i think is better), build up to like 70ish mana, use the first part of the combo, Pop Embolden+Manafication right as they come off CD, and proceed to do your combo without having to hold those cooldowns.

Like i said i havent done the math but i think this may turn out to be a DPS increase since we end up not having to delay our strongest cooldowns.

TLDR: You guys think its a good idea to spend mana on a single part of combo just to decrease it to levels where we can use Manafication+Embolden without having to delay it?
