I can understand that. But Draw Steel’s power roll mechanic just fits you into 1 of 3 tiered results by basically a table lookup.
So a roll of 3 on 2d10 but with double edge just grants the middle tier result which normally requires a 12-16. Practically getting +10 bonus for pitiful dice roll. But then the same double edge escalating a tier when the result was a 12, if it was two +2 (a +4) it would sad trombone into a 16 result getting a same tier 2, but because Draw Steel makes a double edge escalate the tier result a 12 goes straight to tier 3 best result (normally 17+).
I do like that double edge plus a single bane results in still having edge, none of the single disadvantage cancelling out multiple sources of advantage infuriation.
