On my quest to level all jobs to 80, my next in line is MCH (which is currently sitting at level 77). For reference, I was almost exclusively a healer until Shadowbringers came out in which I immediately dropped healing for Dancer and have played Dancer almost exclusively in end game content (including Savage).

A part of my challenge in playing MCH correctly is undoubtably experience, but what I've noticed now that I essentially have all my tools is that the engagement factor seems to be managing all your cooldowns. I need to focus on using Drill/Bio Blaster, Anchor Shot, Wildfire, Reassemble, and Autoturret (later Automaton Queen) on cooldown while ensuring my Hypercharge phases aren't causing these cooldowns to clip. Before when Gauss Round and Ricochet only had 2 charges max, I also wanted to make sure that they weren't going to CD overflow when using Heat Blast, though that's become a lot more comfortable with the charges now increased to 3.

I find myself paying a lot of attention to all these CDs to try and make sure I'm using them correctly, but I assume this gets a lot easier with practice? If so, I can understand why it might seem more brain dead, but thus far I find it a lot to pay attention to.
