Brutal Rush I can 'feel' an improvement during levelling when just using it regardless of the situation but I want to quanitfy it's benefits in PK and learn when to use it and when not to. It has one round of lag and the effect seems to last roughly as long as entwine.

How similar is 'brutal rush' to orc 'crushing assault'? My guess is not at all.

Brutal rush true or false:

Reduces the number(or chance) of swings one or both opponents get, and penalizes further if either is wearing anything larger than a dagger?

Prevents fleeing. (probably not)

Restricts/penalizes skills both passive and active that require mobility (concealed, rebound, malleability, pincer, impale, spin, distance and most hunter skills, etc.)

Makes it harder to parry or dodge for one or both parties?

Is this skill worth using on warriors? Mages? Assassins? Axe specs? Sword specs? Pole specs? Spear/staff? Dagger?

Dex is important for everything about this skill. Does it mean it's not worth using for slow races (16, 18, 20 dex) against quicker ones (20, 22, 24, 25) without crippling/entangling them first?

Is it possible to penalize yourself for using this skill other than the obvious pros/cons of using a dagger or your bare hands without predator stance/unarmed defense/ironhands?

Is it overall a defensive or offensive skill? Both? Neither?
