Going to keep this simple.

A way to combat the ever increasing HA that is being handed out in the game.

SO similar to Bulwark stance BP Flip and slap... assassins have a move which enables them when timed correctly with the enemies HA attack to dodge and inflict a small amount of damage on the opponent. It's not stopping there attack you will dodge it and they are free to continue into the next HA Armour strike if they wish. Obviously it would need a fast recovery time for the assassin.

Like a Bull fighter dodging the charging bull kinda thing ?!

Low reward, Medium risk, gives heavy spams something to think about which after the raider rework and the new character in Dominion for any assassin is a reaaaaaall thing atm since it's just a slapping contest.

What I don't want is a useless dangerous move like deflect....

The assassin class is having a tough time atm and HA is one of the main causes, simple way to make HA slightly punishable and not such a safe bet sometimes...

Reflex guard should have some bonuses !!

just a thought...
