>Spontaneous INT-based caster with limited spell list/spells learned that are tied to your subclass
All casters are spontaneous now.
>Spontaneous WIS-based caster (ie., Favored Soul from 3.5), spells learned are tied to the subclass/domain your divine touch came from
Favored Soul was already done as a Sorcerer subclass. Clerics are already spontaneous, and they do get extra spells from domains.
Tying into each of these, 5e clearly doesn't want to do the idea of having new classes that are just existing classes with more thematic spell lists.
>A "tinkerer" support class (like an Artificer)
Yeah, I can agree to that
>Psionics with subclasses explaining what it can do (one melee dps, one for ranged dps, one for healing/buffs/debuffs)
I'd rather the Psionics subclasses not just be WoWspecs, but rather diciplines like Telepathy and Telekinesis. At best, have an extra option where at an early level they can choose to either get extra armor proficiencies and extra HP each level (for a Psychic warrior type) or extra power points or spells known (for a more mage type)
>4th edition's Warlord (able to use something like superiority die to let team mates move around on his turn, get a free attack, ranged heal, etc., while he bashes skulls in)
I do think they need to have a better take on this, though I still feel like they could almost fit it in to the existing class structure. Currently you can do it decently well with a Battlemaster fighter and a Mastermind Rogue, but I think what you'd really need for a successful one is to have more Superiority dice, but smaller ones, and on someone who's not quite as combat capable.
