I want new skills the most

Unless they add a character skin that lets us use the appearance of the Scion on any character, then I don't really care about any of the potential upcoming classes. Templar, Duelist, Shadow. Hoping we see something new before 1.0.

What I really want is more skill gems for the existing tags. It would be so nice for those of us that don't play Druid or Templar to also get a couple new Elemental, Spear, Occult, Mace, ect. skills.

I see a lot of complaints about being forced into certain playstyles. Such as how Werewolf has to use Cold damage. Adding like two new skills that Bleed and a Support gem that adds synergy between Cold and Bleed. Now Werewolf can be Cold, Bleed, or a mix. Just using that as an example but all existing tags could use more. I'd love a couple more Spear skills that deal Fire damage. Skills that have been in since 0.1 could use more such as Elemental.

I know designing skills in PoE2 isn't easy because they want skills to feel more distinct than in PoE1. Even if I'm not interested in new classes, they still bring new skills with them that I can mix with other classes such as my Stormweaver using Volcano. If Duelist/Sword comes with Elemental Hit, then I'll play Sorceress with it so I still get something from new classes.

It would be better if they change existing skills so that we actually want to use 90% of them.

Like 90% of the skills in the game, I just look at and never want to use. Too many things everywhere like cooldowns, charges, infusions, sustain issues. They've decided to go this route and have made the skill system this way so I doubt it will ever change. They've managed to make skills mostly unappealing. It's just the D4 generator/spender system with different names.

I guess it's easier to balance things when a skill only works with 2-3 other skills or when you do these 2-3 other things and nothing else. However we are then playing the devs builds instead of our builds.

I get what you are asking for but they are already struggling to dev 2 games at once. Let them finish the videogame and ask for that after 1.0.

It's safe to assume that once every class has finally shipped (which seems more and more like it won't even be for 1.0) existing weapon types/classes will receive new skills just like PoE1 received many (many!) new skills over the years.
