If you remember back to some of the older 4e monster design threads, I brought up the point that, without "sourced" bonuses, you lose the tactical flexibility of being able to attack those bonuses. One of the examples I brought up was the case of fey warriors who get their combat stats through magic. And indeed, possibly in part because the monster design system doesn't track stat origins, Dispel Magic is a pale shadow of its original self, and an entire chapter of DnD combat tactics is lost.
Btw, that charm, save ends effect on your friend? Yup, Dispel Magic no worky. I'm not impressed with boasted about how short a spell description compared to earlier editions, when the new spell has precious little to do with the old one.
