I do not really agree in everything, but you have a point on some things you´ve said.
The pure caster classes (wizards, clerics, druids, bards...) have much more options than non-casters. I am not talking about combat or buffs.
I do not know if it is the same in 5e, but usually, there is almost nothing a non-caster class can do that you cannot do with a spell.
Yo need scouting? eye of mage, sanctuary, far view, some invisibility spell, and voila, instantly improved scouting.
You need help in diplomacy? You have discern lies, friends spell, charm, illusion...
Traps? Find traps (ok, you cannot disable them unless arcane trickster or something like that)
Problems navigating desfavorable terrain? fly, feather fall, resist heat/cold, oasis.
Travelling too slow? Wind walk, haste, conjure carriage,
You are hungry/thirsty? create food and water, good berries,...
You need brute force? Bull's strength, tenser transformation, polymorph or summon something to do it for you...
You have to build or repair something? Fabricate!
A problem that is not of the above? Wish!
I understand it gives you more rp options for caster types, but I found it too unbalanced IMHO.
