be too overpowered?

Warriors Cunning 10e 30 sec recharge
3...8...14 sec duration, lets say 11 secs at 12 str.

if so..how about same duration vs attribute but a 45 sec recharge.

imho looking at the 9 sec duration vs 60 sec recharge is like seeing your only child drop out of college, pick up a drug habit and end up alone shivering in some alley. Travesty.

ps if the 45 sec recharge IS still too overpowered, how about

Warriors cunning [E] 10e 30sec recharge

3...8....14 sec duration.

Or is it fine the way it is?
