Coco and Lynnabel please reconsider the change in Keen weapons, not asking to keep the [W] but change it to something "fun".
We already are encouraged to reach high armor penetration, plus there's a 100% fortification reduction at endgame.
maybe good change would be vorpal hits on enemies leave them vulnerable to critical hits for 3 seconds.
This is only an idea, but I believe Lynnabel is better making "fun" effects.
