MCH future changes from the live letter

[MomoOG]

No other job gets a free gimmie before a pull even starts. Dragoons don't just start at 2 eyes when they BotD. Starting at 0 heat is fine.

What does what other classes have to do with anything? Some random rule that needs to be enforced because? Hey look MCH himself can free gimmie ammo for himself and MNK can build Chakra stacks before a fight. Or maybe you want to create some sort of special rule about what counts as a free gimmie resource.
The point is that with the current heat gain mechanics, a MCH trying to go into overheat on the first wildfire overload becomes clumsy. Other classes don't have to deal with a similar problem.
