Quake vs Modok interactions are buffed on one of his light attacks.
Not sure if this has been logged, but I have noticed lately that when you are using Quake against Modok, one of his light attack animations (where he goes very low down and sweeps with his arm) will not actually trigger an evade if you are charging heavy. It is almost like the attack is too short to make contact even when he is standing right on top of you. This is very disruptive if you are trying to play Dex-style quake, as you will assume this attack would hit and then try to Dex only to have it drop your heavy instead.
Has anyone else noticed this?
