The exact same balance issues 5e has already as well. Just that casters have 3 daily powers from level 1 not 9.Essentials was probably too late (and within 4E concept of balance, I think they're problematic. The moment not everyone has encounters and dailies, you risk getting into balance issues between 1 combat per extended rest and 8 combats per extended rest. But personally, I'd ditch "daily" combat powers anyway.)
Also there is only 1 concept of balance, you can judt care about (4e) or not (5e)
