Currently missing channels that I hadn't added because I don't know how long they last:
Johanna's heroic "Falling Sword" has an unstoppable X seconds cast period. Stukov's "Lurking Arm" casting time.
- Stukov's "Massive Shove" maximum cast time if it doesn't hit any hero.
- Stitches' "Hook" maximum cast time (including time the hook travels back to Stitches), including level 16 range extension.
Garrosh's "Groundbreaker" ability has a X seconds cast period.
