Fleeing mobs and miss rate goes through the roof
 

What is up with my miss rate going way up when a mob is fleeing. I'll hit over 90% of the time, then mob flees and 7 misses in a row. Happens way too consistently to not be coded in somehow to miss more when mob is fleeing.

I think it is server and client disagreeing on position of you/mob in a way that server forces a round to fail but client misreports it as a miss instead of out of range.

you will recall the luckiest day of your life and vividly so your unluckiest. But you will scarcely recall the countlesss average days between.

Meanwhile I can't remember the last time a mob missed me if it was at my back

Well, yeah. Because you can't Dodge/Parry/Block/Riposte hits that come from behind you.

You can block from behind as well, from the wiki

Skill Block
Like Dodge, Block allows a character to avoid all damage from a physical attack. However, unlike other defensive skills, block can defend against attacks from behind the character.

Oh yeah. Just the other ones don't work from behind.
