Depends where you ride. On the roads, probably not. But on trails if you spin-out your rear wheel against something hard, you'll loose studs. And spin-outs are easier on emtbs.
RC3 Zebs seem to have the opposite problem, hard to use all the travel and getting it to bottom out. At least 180-190mm RC3 Zebs are very progressive towards the end of travel.
There is no motor resistance. You lose 100-500W of power from your legs and you are going to feel it. You need to be prepared for the cut off, drop a gear or two lower before the cut off and see it that helps. Also ride the jump line with the motor off and see how that goes.

How is that extra 30mm ruining the ride? With emtb you don't have to care about pedalling efficiency. I like Pole's philosophy of having trail and gravity tuned platforms without being too hung up on suspension travel.
