More then once I've seen a familiar pasted in the first few rounds of comabt as a way to injure a wizard, so I usualy avoid them.

I change into a Treant and share the spell with my familiar who turns into a treant right next to me. We both proceed to pummel the heck out of the target. Probably works even better with recent spells like 'trollform' etc. As long as you stay within 5ft of one another, the share spells works wonderfully.
