For all I know 5-6 high gears on big ring and 5-6 low gears on small ring is good.
lowest big ring and highest small ring gears may actually be similar ratios?
On an 8 speed bike, I'd be annoyed if I could only get to 5 or 6 of the eight cogs in the rear without rubbing. It should definitely be able to be setup so that you could use the entire cassette without any rubbing should you want to (yes, cross chaining is "bad" but it's also useful quite often depending on where you ride). Unless your bike has very short chain stays, I'd be surprised if you could not dial out the rubbing (with the correct chainline to start of course).
