JKL Heroes Arise , Cooldown Manipulation

The root cause of this is how they coded the "cooldown" for Heroes Arise. The intended effect (per the code on .gg) is:

1. At the start of each ally non-Old Republic Jedi turn, set the cooldown of Heroes Arise to max
2. Then reduce it by 1 for each turn ended by a non-Old Republic Jedi since the last use of the ability (including the Jedi who used it)
   
   

Leia's leadership applies immunity to effects using the cooldown_delay tag, which is how part (1) above is tagged in Luke's leadership. Thus part (1) cannot trigger and the cooldown stays at the last value seen. This is best observed at 39 seconds in the video when Jocasta uses the ability:

Character            | Turns Ended Since Use | Calculation | Cooldown
JKL                         | 1                                            | 10 - 1            | 9
GL Luke                | 2                                            | 9 - 2              | 7
Cal                          | 3                                            | 7 - 3              | 4
Cal's bonus turn | 4                                           | 4 - 4              | 0

I know we didn't technically see the ability on the bonus turn, but it is just another turn as far as the game is concerned. If not 0 on Cal's turn, then it flipped to 0 on GL Luke's granted turn.

The only spot this appears to break is when enemies get in between. In the video, each enemy except Admiral Raddus provide a -1 reduction to the cooldown; he is the only enemy that after his turn, the cooldown proceeds as noted above. This happens at the opening and end of the video - taking the opening at ~10 seconds, we get the same pattern as above

Character | Ally Turns Ended Since Use | Calculation | Cooldown
JKL              | 1                                                    | 10 - 1            | 9
GL Luke     | 2                                                    | 9 - 2              | 7
Raddus       | 3                                                    | -                     | -
Jocasta     | 3                                                    | 7 - 3              | 4

At 27 seconds other enemies intermingle and reduce the cooldown like discussed:

Character | Ally Turns Ended Since Use | Calculation | Cooldown
JKL              | 1                                                    | 10 - 1            | 9
Jyn              | 2                                                    | -                     | -
Jocasta     | 2                                                    | 9 - 2 - 1        | 6
R2                | 3                                                    | -                     | -
Jocasta     | 3                                                    | 6 - 3 - 1       | 2

I don't see from the code available why Raddus would operate differently than other enemies. He is also one of a small set of characters that naturally have a 4th non-ultimate ability so perhaps that plays in somehow. This is also the only ability I have seen that unconditionally sets its cooldown to max once used; maybe it's a red herring but even Thrawn and GL Luke's granted abilities don't do this in their flow.
