There's a section in my notes about making all Geist Schritts go on CD for 2 rounds if it doesn't trigger properly that is also an option.

I actually think that on paper it'd be a good idea, in actuality it'd only cause players to only use skills that target locations like sidecut/crystal rose/korkenzier/shinken etc. just to force GS on cooldown

would this prevent that sort of abuse?

If it's a skill that doesn't cause GS to end, then it wouldn't cause this.
