A member of ours by the name of formerdeathcorps made quite a few impressive ASM hacks, among them was the ability to change Reactions to Anything on the Formula Hacking page. I decided that this should be put to Great use, and now Reactions are now set to something else.
That something else is Wall's CT. In the coming days I will remove Wall's "benefits". And give it 80 CT (or however much is needed to balance about 10 turns worth through each patch). Wall will be then be called Adrenaline.
What Adrenaline will do is at the Very start of battle, there will be an 80% Chance of your reaction going off. As the battle wears on (to represent fatigue) your reactions chances begin to drop steadily, before "Adrenaline" is gone completely. This also applies to your enemies though, so it is just another layer of strategy to keep in mind.
