Having a default that preselects every choice, keeps things simple for players who want simple.Different strokes for different folks. The spellcasters presently all get to pick new things each level - new spells. The non-casters don't.
Both of these should be fixed; we need both simple casters and complex and varied warriors. Varied warriors seem to be well in hand.
But I also recommend for example an elementalist pyromancer whose only spells are things like firebolt, scorching burst, fireball, fiendfyre, cloak of flames, and teleporting between fires. But e.g. their fires get caustic and stick to things as they level up delivering damage over time as well as doing extra damage.

To be fair, 13 preselected spells is simpler than 113 optional spells.No it doesn't. 13 spells that each have different effects in play and are situational is 13 spells and leads to analysis paralysis. It doesn't matter whether those 13 spells were all pre-selected or you had to dig them out of a list of 100. It still leads to analysis paralysis.
Worse yet it leads to analysis paralysis in play - which is harmful to everyone rather than analysis paralysis at level up which is easy to deal with.
I want a stronger disincentive for single level dipping, possibly including a minimum level requirement before you can change classes. I would also be happy with eliminating multiclassing altogether and replacing it with modular class features similar to the recent UA. That would allow the meaningful choices every level most people seem to want.I would be ok with looking into eliminating archtypes at 3rd level and replace it with multi-classing, even keeping the single class. This allows the option of changing your character over time with new abilities. Give a new level when you get archtype benefits. If someone wants to keep straight class, then they get more single class abilities- not sure if they would/should be better than the choice of multi-classing.
Make a new path/prestige class at higher level/tier. Somewhere over 10th level so some games can use it and other games may never get that high. This would make for a cool bad guy with prestige powers that the PCs do not have yet.
