Overheat Control

This one is a weird one, but once again an issue with MCH, seem to be getting a lot of that lately, huh Square? I'd almost feel personal if I didn't know better.

Okay, so Heat Blast is supposed to be this big burst of damage thing, right? You get 3 blasts of 6k every once in a while for a total of 18k damage, big and impressive, even though some classes can just, y'know, do that kind of potency right off (Assassination's 14k comes to mind.) So fair enough, it's a decent chunk of damage to be done over 4.5 seconds, it could use a little bit more considering you have to spread that damage like that but that's always the case with MCH anyways.

The issue itself is in how you GET there to even BEGIN to Heat Blast. You have to maintain a steady 5 hits of a skill with walkcast and you get it IMMEDIATELY, no chills about it, you either start spamming Heat Blasts or just lose them. If you stop spamming those Blast Charges for any reason, either because you need to run away, guard, use your machinery and Scatter Gun it is gone. And even comes INSIDE of a GCD window since the 5s begin once the 1.44 cast is done in a 2.4 GCD, which means by design you lose 1s of Overheat even if al you're doing is walkcasting your way into it.

And that is to say nothing of when Overheat comes at a bad time, sometimes you're just Overheating to a dead body so now you need to Tab to acquire a new target and if that costs you more than half a second, you just lost a Heat Blast. Or you really need a Guard right now because there's this annoying Ninja throwing his stuff at you, there goes your 5s Overheat completely gone inside of your Guard window.

So here's a couple of suggestions that doesn't require a separate Hypercharge button, since you seem to be really inclined to not give classes much more than 6 buttons:

- Remove the duration of Heat entirely. That way Overheating can be a counting your shots and when you see that 4, you know the next one will be an Overheat. That way you can Blast Charge, weave your Wildfire and Heat Blast away to activate it. Losing Heat during a battle with only 15s is way too easy to do (Guard + Scatter Gun, a basic survival tactic, will already cost you 7.4s of it, that's half your timer right there. If you don't have health to re-engage you just lose heat.)

- Activate Overheat only when you first press Heat Blast. Which means keep the Heat with a duration like it is right now, but only Overheat when you first press Heat Blast, giving us control over the Overheat 5s window instead of just being dropped on us. You can even have, like, a buff like "Overheat Ready" that lasts for 20s and reads "Your next Heat Blast will activate Overheat." Then reduce the Overheat window to 4s because that would make it 3 Heat Blasts, instead of 5s which would allow for a 4th one.
