There is the problem, u mentioned it yourselve: The Modafaka instastab on pikes!
I'm a bit confused by your wording. By "pike" are you referring to the 2d polearms (awlpike, ashwood pike, etc) or the "Pike".
Awlpike and ashwood pike have a near instantaneous stab, this is true.
Pike requires an enormous amount of wiggling for the hit to actually register, otherwise it glances.
This is the reason for the thrust stun effect, just like I explained in that post. They get that first hit off, and all you can do is block, HOWEVER, after that they are stunned for a brief moment. On the faster weapons this is enough to give you time to get an attack started such that they have to block you. On the slower weapons it can even give you a FREE HIT if timed right.
