I agree, and I'm surprised they've done it. I speculated before the announcement that a Krogan Battlemaster would be a Charge-less Vanguard, because a krogan Vanguard with Charge would be unbalanced. I guess they found a way to handle it? They did mention that battlemasters aren't very nimble without Charge, so perhaps that's the balance -- they can't charge something nasty, then dive away like the other Vanguards, which means they'll need a good longer-range punch to handle Banshees/Brutes/etc.
