## Fire Mage
## https://github.com/simulationcraft/simc/
## September 11, 2022

## Changes:
## - Use fight_remains rather than target.time_to_die for last-second ability usages.
## - Loosen cast requirements for Combustion (i.e., don't hold it for a fresh Meteor cast).
## - Enable strict checking on a few forks in the APL to reduce workload.
## - Adjust a Pyroblast entry that does not model well in-game (sim tested at no significant DPS impact).
## - Convert all buff.X.react entries to buff.X.up, an almost insignificant DPS gain in sims.
## - Use hardcoded variables to reduce CPU workload.

## Executed before combat begins. Accepts non-harmful actions only.
