The idea is that the scaling should keep pace. At 11 you get three attacks, but your cantrip does three dice of damage.
But the reality is that your cantrip needs to do ability bonus damage for that to be true. (Or something like advantage on the attack, or a cantrip triggering a difficult save like an Int save, or something)
War Magic plus Eldritch Blast plus Agonizing Blast in a melee form would be something.
Why does it need to be melee? Agonizing Blast plus a heavy crossbow attack is a pretty nasty ranged combo without investing any feats or spell slots.
And for me, multiclass combos like that are what War Magic is really about. Once you have War Magic and a SCAG cantrip, you have DPR that's competitive with a straight fighter even if you never take another fighter level (though yes, the pure fighter can pull ahead with feats and magic weapons). This frees you to focus on a caster class for more spell utility, or on sweet combos like the one above, or sorcerer for Twin Booming Blade so you can be a very sticky tank, or abjurer if you want to be absurdly durable.
