Using a 1-1-1 5* Kang in PvE vs non-tile movers.
Kang's blue does damage on activation, as per his 3* Blue power.
Kang's purple passive generates blue AP on CD expiry Instead of CD destruction (friendly and enemy).
Edit: only purple cover seems bugged. Blue seems fine.
Does the purple not generate blue AP on destruction (non expiry)?
Misty Knight's yellow heals allies when a fortified tile is destroyed. IIRC, this was healing when fortified countdown tiles expired. If that is working correctly, it could be that a countdown tile expiring is considered destruction of the tile. The tile does remove itself afterwards.
If this is the case, the text on Kang's power perhaps should be updated to include this, so that it's clear that it's working properly.
5Kang does not generate any blue AP on CD destruction/match, regardless of friendly vs enemy vs fortified vs non-fortified.
Edit: 3Kang vs 5Kang have very clear difference in description, expiry vs destruction.
Edit 2: okay did more investigating. AP gets generated on destruction, and not on match. However, CDs are generating AP on expiry, which didn't seem right.
