Actually it already scales.
120% at lv1
160% at lv15
2s cd at lv1
0s cd at lv15 (but capped to 1s)
Ah ok, didn't know that, or perhaps my older version doesn't have it yet, will check.
How to implenment adding minor aoe to it?
If that's not OP, how would one go about doing it?
Perhpas adding adding range for a start, but not too much to the point of countering ranged opponents, since there are opponents that can hit you from a small distance or knockback, preventing RR from triggering.
Can it trigger ALL passives?
If not, it should, would combo great with Shred.
Also, if in Frenzy, does every RR hit become a crit?
