Yes. This is rubbish. Makes keen mostly useless as often the expanded crit range is picked up from IC anyway.
Accepting at face value that the +W change is needed in the bigger picture rebalancing, can please have something more useful than a bypass that most will have had to build for anyway, as otherwise relying on a 1 in 20 chance is wholly insufficient? Something small but useful maybe like +5 to hit or a flat 5MP would be better.
