I don't know if a 5-1 is really asking your setter to not hit... You have more offense when your setting from the front row, than from the back.
You can jumpset and block those tight balls. Dumping is FAR more valuable than a hit from a setter.
If your only setting back row - the defense will never jump with you. If your front they have to respect you.
Besides... A hit on two instead of a dump is always nice
