Is it just me?

[Disco]

Alright my fellow Swadians, our subject in this topic is pretty trivial. But I want to learn trivial boring details both in real life and here. 

So; when a big fella like Jotne, berserker, varangian etc. hits me when I'm holding my shield, a temporary(a sec) shock happens that prevents me from attacking him immediately. I think all the enemies with 2h or polearms have this ability.

I mean this is not really important but I find it annoying. Does that happen to you as well?

This is a feature in warband.
(Excerpt from Mount and Blade Wikia)
"Weight: Affects your overall encumbrance (the speed at which you move on foot and travel). It also increases the chances of the "stun" effect when you strike an opponent's block. The collision of a high weight weapon with a low weight weapon sometimes results in a "stun" effect where the person carrying the low weight weapon cannot respond with another strike. During this period the person with the low weight weapon can only block a second swing from the heavy attacker. With the roles reversed, a heavier weapon will not be stunned by a low weight weapon."
