Heck no it won't suffer! Especially with Nottingham, you'll get a high-attenuating, dry beer. If you were using a different strain such as an English variety that leaves residual sweetness i would think it would be farther off from the original.
I got 68% efficiency on my first AG and am pretty sure it will taste good (still in primary).
