Is Inspired Zeal limiting balance?

It's a leader that abuses strong orders, so I think it's a problem, in a world where in other factions you need to think the proper moment to play a powerful order card for it to survive, Inspired Zeal says "f that" and just plays an over the top order card without any of the supposed disadvantages of playing an order card, Raffard's Vengance is supposed to be balanced by the fact that it'd need to survive for a turn, along with Selkirk, Anseis or similar cards, order keyword is supposed to be a disadvantage of a would be strong ability, it's supposed to be a drawback of a powerful play that, otherwise, would be broken on deploy, that's why order cards (the ones without zeal) are not active until your next turn, to give your opponent a chance to disrupt a strong ability, so, the question I make, Is Inspired Zeal limiting balance?

I'd say yes, because is currently the only leader that is being played in the strongest NR deck and is limiting other NR leaders to shine properly, why the hell would someone play Stockpile if IZ provides strong Raffard, Duels and more, even boosting them out of regular removal range in the case of Raffard, but, what do yoy think?
