While I'd never kick anyone for doing so, I've gotta agree, knockback skills are the worst thing I'm group content. I've told my FC many times that if they knock something back, I'll stop tanking it.
We all have situational abilities. It's great you'd like to use your full toolkit, but this is like a BLM using Sleep when it's not needed, or a WHM using regen between pulls, or any other situational ability.

It's not about you, it's about the party. That might be tough to deal with but you might want to suck it up and end up more skilled in the end.
