Brawler finishing move tweaks

[Bad Badger]

Right now Brawler's finishing moves are kind of sad--a lot of players don't invest beyond Uppercut, and the ones that do tend to skip toward Haymaker. I have a few ideas, let me know what you think (or toss in your own!):

Concussive Punch -> Double Lariat: Spin in place with your arm outstretched, striking all adjacent targets for x% weapon damage. If you have 3 or more combo points, you will strike each adjacent target twice; 5 or more combo points will allow you to take a step between strikes/put one of the target's active sustains on cooldown for each strike that hits.

Body Shot: Increased resource loss for the target, and with 3 or more combo points, halve the remaining cooldown of a random finishing move. With 5 or more combo points, completely reset the cooldown of a random finishing move and delay the loss of combo points by 1 attack (allowing you to spend them on another finishing move).

Combo String could give additional benefits for finishing moves that spend more than 5 combo points, such as a third strike for Double Lariat, increased damage bonus for Haymaker (10% ->15% per combo point?), etc...

Opinions?
