# Changes:
# - Use 'time_to_die' instead of 'target.time_to_die' for last second CD usage.
# - Redo priority forks for rotation.standard/frozen_orb/no_ice_lance.

# Single Target
# Without GS, Ebonbolt is always shattered. With GS, Ebonbolt is shattered if it would waste Brain Freeze charge (i.e. when the mage starts casting Ebonbolt with Brain Freeze active) or when below 4 Icicles (if Ebonbolt is cast when the mage has 4-5 Icicles, it's better to use the Brain Freeze from it on Glacial Spike).

Difference between shattering Frostbolt with 1-3 Icicles and 1-4 Icicles is small, but 1-3 tends to be better in more situations (the higher GS damage is, the more it leans towards 1-3). Forcing shatter on Frostbolt is still a small gain, so is not caring about FoF. Ice Lance is too weak to warrant delaying Brain Freeze Flurry.
