Better, but not über. And in this case, the wizard would have attacked 3 times on a 3+ to hit, 3+ to wound against a 2(3?)+ armour save, and get 3 4+ to hit, 4+ to wound attacks back. Granted, the odds get better, but I feel a wizard is better served with a warhorse or a unit of bodyguards...
When facing "the unknown army", things are quite different...
