It's well known that evenly split multi-classing is death for spellcasters. That's very specifically why prestige classes like Eldritch Knight, Mystic Theurge and Arcane Trickster exist -- to make multi-classing spellcasters possible without utterly gimping them.
If your goal is to utterly gimp the PCs (as spellcasters), then this will do it. It's a popular way of enforcing a low-magic setting.
But if your goal is to play normal-magic D&D, you may not be happy with the results.
Note that many non-magical classes multiclass very nicely -- Ftr 10 / Barbarian 10 is decent, and Barbarian 10 / Rogue 10 is excellent.
