[Chaos]

Two suggestions:

1. I'd say Dirty Fighting should be a bit stronger, like +5 per rank. Or, perhaps, lower the target's critical evasion by a % alongside the +Hit.

2. Unfortunately, the typical 'Die Hard' mechanic from SL1 and some Tabletop games doesn't work well in SL2's system. What if it allowed you to act freely for up to (Rank) turns after being reduced to 0 HP, unless you take accumulated damage equal to some large % of your Max HP?

Otherwise, these are actually pretty good suggestions.
