If you’re talking about Feed the Meat and Embrace the Pain, then you’re wrong: FtM is always active regardless of what shield you have and EtP is only active while your shield is down. You also have Empty the Rage, which gives a bonus when your shield is down, and Salt the Wound, which is only active when you take health damage - when your shield is down. K can get a lot of use out of a FH, but I still say a RR is better because of the extra health and DR - a lot of Krieg’s skills work better the more health he has (RtB, Elemental Empathy, melee in general, etc.)
