The whole thing with zoners vs Leatherface is that EX BF3 is a move that exists. You blast through a projectile and you are plus enough for run up Oki AND it throws the opponent to the corner. However it's when the opposing zoner has efficient ways to deal with this armor that things become and issue. Example, Full Auto breaks all of Leatherface's armor for free (Hence why Pretty Lady is the only variation to pick there) another example is Cybernetic. He is happy to spend the bar and make you waist his with EX knives. If they can't break that armor easily, you are going to get in eventually. Leatherface lives, breathes and dies by his armor. His armor is why people respect the absurdly negative Berserker cancels (that along with just letting it rip) armor is why people think twice on wakeup (Leatherface's armor actually hurts enough for people to start respecting it) his armor gives him 50/50's whenever in any variation (DB1 is reactable tho I believe at 25f.) all in all, zoners can be annoying but only a couple give Leatherface a particularly hard time.
