Rotation
MCH has the most uninspired rotation in the game, DNC has flourish opportunities, BRD has dots and songs to worry about, SAM technically has 3, DRG and MNK has weakening and buff rotations, even tanks like WAR and GNB have more unique rotations not being DD. its saving grace is its abilities and its 2 not OGCDs. MCH flows so unnaturally as more often then not your 6 freebie skills are on empty as theirs no benefit to keeping them and the only optimal way to use them is to spam em, waste not style. To recharge them isn't so fluid either as its combined with the "optimal" wildfire button so awkwardly and is rather disjointed from the rest of the kit. As for Drill and Anchor, they are GCD skills so they feel like 20 sec/40sec extensions of the rotation but not apart of the rotation and unlike Anchor which gives you 20 Battery, Drill does nothing but halt your rotation every 20 seconds, and for reassemble to pair up with. When your not doing that, your pressing a button, either to summon Queen or its time to Wildfire! Latency issues has been done to death so it goes without saying. As you overheat and Wildfire you do the exact same thing you have been doing Recharging your G/R but make sure to press a 6th weaponskill and as your doing this waste your G/R inbetween blasts. No Guass and Rico dont contribute to wildfire..nor does your turret, and doing any other skill punishes you for some reason and heat blast is locked and acts as literal dead weight on the hotbar instead of transforming from a previous skill since we arent aloud to use anything else with overheat speed. MCH has many of these odd skill choices and its logic comes to question the more you think about it. A good Job flow like a river with every crease ascending the stream, while MCH plays like a 3 different ponds with no link to connect them yearning to be whole.

AOE
A underrated topic is a Jobs AOE capabilities. and as for MCH ...well its better than 4.0 but has the same "disjointed" issue. Ricochet is my personal favorite skill concept and all but doesnt work well as a AOE as MCH has no way of recharging it in a AOE situation unless you Heat Blast a target at least twice but even then it just ends up being clunky and not worth the effort. Flamethrower used to accumulate heat now its one of MCH forgotten skills outclassed by Spread shot+ Auto crossbow. I doubt it would break the game to allow flamethrower to gain 5 heat per tick (55 Heat) with its restricted mobility and every 60 seconds it should suffice for what its doing. Also why does Auto and Spread do the exact same damage? More importantly why is this skill gated behind overheat? When Skill bloat is a common issue youd think SE would replace it, but it wouldn't feel as great to overheat it? idk also Bioblaster is fine as is, its a dot thats its purpose even if its only tie to the rest of the job is sharing a recast timer with Drill.
