MCH Overheat should activate automatically

[IronIngot]

Wait? You didn't like automatically sacrificing an animation-lock's worth of Overheated's 8s duration, dropping it from max 6 (8/1.5) shots to max 5 (slightly under 7.5/1.5)?!

Personally, I'd slightly prefer a different tack, if only because I dislike button-bloat:

• Hypercharge Overheats your next 6 shots; 12s max duration.
• Heat Blast, once acquired, replaces Hypercharge while Overheated.
• Auto Crossbow, once acquired, replaces Spread Shot / Scattergun while Overheated.

Yeah removing the animation and giving X amount of stacks that last Y time (like WAR Inner Release) to use Heat Blast and Auto Crossbow is also a good idea.

How about this:
- Get to 50 heat
- Heat Blast and Auto Crossbow become available
- When used they consume 50 heat and fire off right away
- You get 5(?) overheat charges lasting ~15s
- Each use of Heat Blast or Auto Crossbow consumes 1 charge
- When you consume all the stacks you can use another 50 heat or continue your rotation

It's 2 buttons, up from 1, but the added flexibility would definitely be worth it, imo! Definitely add some further audio and visual element though so that you know when you're down to 1-2 shots, though, or else people might accidentally spam into a second round of Overheated that they'd had meant to save for raid buffs. (We see similar protection for stack-based systems already applied to all but Requiescat-Confiteor.)

Now, the harder question, though... could we ever get back some manner of Heat mechanic that gives MCH more to do than just 1-2-3 and hit CDs as they refresh?... >.>

:: Final bit: Let's please let the reduced-GCD of Heat Blast and Auto Crossbow scale with GCD speed.
