Rogue - Assassin Changes

[Grailhawk]

Some comments:
~ We are considering making Weakening Strikes reduce Melee Power of enemies with an Assassin's Mark by 10 + 1/2 Rogue level. That means a level 20 Rogue will be getting an extra 20% mitigation.

This is good but I'm thematically I would prefer more abilities that prevent mobs from attacking a rogue (like bluf, feint).
