Alright, so as has been discussed, when coming at things from an NPC/FM perspective, the and flips get flipped because NPCs dont flip, their AVs are static. It seems easy enough to deal with ( attack just gets switched to df flip) but the problem comes with cheating.
If my NPC enforcer; John Q Murdermire focuses his Sledgehammer strike, this will impose a flip on my Fated's defense. Who now cant cheat due to the flip. A suitably overpowered experience.
So what I'm doing to work around this, and continue to make my life significantly more math free is applying a +/-2 modifier to my NPCs acting value. (1d14 avg is 7.5, 2d14D1 avg is 9.8, so roughly a bonus of +2 for a positive flip)
Its a lot of words, and my players dont even know Im doing this, but I feel a simple plus or minus 2 works out pretty well to avoid situations like the above with John Q
