I'd say put fairy skills separate from the GCD again, so you can use them independently during your own heals rather being than SCH oGCD's. Having fairy heals that you can use even during GCD casts would become a SCH strength, a reason for having a minion and feed into that class identity.

I also agree on the potency. Even if they cut the potency, there's no reason why the tooltip can't reflect that. Especially when AST Star is also counted as a minion yet it has similar potency to the tooltip.
