I think that the magic system for D&D is SERIOUSLY flawed. There are so many spells it's nigh impossible to remember them. What needs to happen is there should be a single spell, which can duplicate the effects of rope trick/tiny hut/mordenkainen's mansion/etc.
How about a single spell that creates ag's scorcher, fireball, burning hands, flame strike, etc?
Or another one that duplicates invis/greater invis/superior invis
Or levitate/fly/overland flight.
There are so many spells that aren't "flavorful," they are just bland reproductions of others spells, except at a higher power level.
