Since its been said that we will be getting a 2nd group of merits of some sorts, an idea I had for one of the new merits would be Samurai's Charge.
Samurai's Charge would work as follows: Grants your current overwhelm bonus to your next weaponskill regardless of where you face your target.
This type of ability was amazing for Thief with bully letting you sneak attack from anywhere. This might be right up our alley for the upcoming additions.
