Currently, when a wave is completed in a wave node with a high damage attack and a character in the next wave possesses an ability triggered by damage (2* Storm yellow, 3* Capt. Marvel Yellow, Thing Yellow, 3* or 4* Deadpool black, etc), that ability will trigger immediately, before the next wave has even spawned. This occurs even when the character triggering the ability requires that the damage target them specifically (such as Capt. Marvel yellow, Hulk black, Red Hulk red).
For example, take this hypothetical wave node:
Wave 1 - Soldier, Soldier, Soldier
Wave 2 - 2* Storm, 3* Captain Marvel, 4* Deadpool
If I down the first 2 soldiers and then kill the third soldier with a high-damage ability (say, 3* Cap red for 4K), I will immediately get hit by Storm’s raging tempest, my opponent will generate red and black AP from Captain Marvel, and an X-Enforcer countdown will spawn.
I thought this might be working as-intended, and that teammates care about their teammates from previous waves, until I saw it trigger on Captain Marvel who specifically has to be the one taking damage for her yellow to fire. I have not confirmed whether the characters need to be in the same position right-to-left for those single target damage based abilities to fire, but either way it is broken.
