No worries 
I can be pretty efficient when I’m able to set aside the time. Glad you like the thumbnails. Thought I should have some way of differentiating the old and the new videos at a glance, and tiny screenshots of the editor aren’t very exciting or informative.
No problem, I could have been clearer. The idea behind this modification is that first you run the code that damages the enemy (and queue’s the current unit’s attack action) and after that you do the same thing, but with the roles reversed. So you need to do first what is done in MoveAttack ususally and then do the opposite. Here is a pastebin of the whole function.
Also, you need to select this ability as the default ability of your unit’s or they will continue to use the old one.
