so then the charge in question would not be a valid point in the argument of "see? zerkers don't suck" 
also, to the conterlag while zerker has a staff issue: every class that can counter charge has more defensive ability than a zerker, period. warriors have the lores and pugil, meaning if you wield the staff, that zerker is gonna be outmeleed fast. monks simply have to prepare properly and the zerker is toast. blademasters in bladerush (or whatever its called) with weapons held low and prediction charge will outmelee the zerk.
my point being that charge flee can be rendered useless just as easy as it can be used.
Except this is a warrior we are talking about 
And no, a blademaster in ironarm stance won't. This is why.
Zerk charge. Add 2 rounds of lag.
Blm disarms after those 2 rounds, add 2 more. Zerk flees, rewields, charges, add 2 more.
In the time it takes you to disarm, he can get, and wield the weapon in the same round as he was disarmed. That is only a viable tactic if you can land certain critical strikes based on anatomy, which I have already stated is a moot point since you pull four rounds of lag from a charge then a crit strike.
Predicting also is ineffective, since it does nothign to stop that lag. Which is the killer. Any warrior will outmelee a blm in a straight fight, blms rely on combat skills, onslaught and crit strike,
