This is a follow-up to an issue I mentioned in the Empowered Channeling bug thread. Absorb Heat often refuses to cancel, whether or not the player is using Empowered Channeling. 0:00 Quick demo showing that shift = block and that, with no other inputs and nothing else going on, Absorb Heat can be instantly cancelled by blocking 0:16 In combat, if you only press to activate Absorb Heat then press nothing else except block and no external effects are being applied to you, Absorb Heat may still instantly cancel during block. 0:22 In a realistic combat situation, with other powers and attacks being rotated and clipped, Absorb Heat will either be very resistant to cancelling, or... 0:32 it may refuse to cancel altogether until the cast is complete, which is a death sentence in Elite raids and makes the power unusable as tank, even with Empowered Channeling. The probability of this bug occurring, in order of likelihood, seems to result from: 1. the player clipping weapon attacks (or really doing anything quickly) in between powers or immediately before casting; 2. pressing any other power/attack input while Absorb Heat is casting; 3. Being struck by an enemy; 4. Jumping during the cast; 5. Starting the cast stationary then having moved, or starting the cast while moving then becoming stationary; 6. Being affected by beneficial/detrimental status effects during cast or having status effects active upon initiating cast; and 7. There is still a chance for it to happen even if none of the above applies. Definitely a bug, as the power is supposed to be cancellable via blocking at any time during the cast, it sometimes just doesn't work. Makes it an extreme liability in fights where we have to block on a moment's notice, (Throne E vs Sea Beast; CoTe vs Murk; SGe vs Tala meatballs; FIe vs Harpies, Phoenix, Forge, and Merciless; and MoMe vs Merciless and, to a lesser extent, Freeze & Ivy), often mandating we swap it out for Mass Det so we can cancel casts more reliably. It also makes it virtually unusable as Tank, even with Empowered Channeling, which is unfortunate because with Empowered Channeling + the Tank role interaction it has it would be one of our best powers for active tanking single targets and self-healing. Note: This has been an issue for as long as I can remember.
