Upcoming Level 4 Skills

Guard, Renewal, Defiant Skills (these could be neat, say if they give the same buffs as Brazen skills, units with AoE specials and blade weapons would have some new options without being OP), and I want Warding Stance 4, in the same vein of SS4. Also having a 50% QR skill probably wouldn't be too terribly busted.

Defiant Stat 4, if any skill needs a Level 4 it's these long forgotten and ridiculously outclassed abilities.

QR4 or some kind of Guard 4 are probably inevitable since they have already been heavily powercrept by Surtry Stance 4 and Vengeful Fighter.

Those new lvl 4 skills are nuts. They make Death Blow 4 look like a joke. Burn a brave celica for 2 extra damage? No thanks. Sturdy Impact they could have made just Atk/Def +6 and it would have still been a desirable skill. Instead it is Death Blow 3, Armored Blow 5, and Wary Fighter infinity (no hp check, no class restriction) all in one.

If they do come out with Swift Sparrow 4 (Swift Impact, maybe?) I can only imagine it will be ridiculously powerful too. Atk+6, Spd+10 and +1 cooldown for the user on initiation.

I wish they would come back and add a new level for some of the nearly useless skills that you never see being used. Water boost, fire boost, etc... maybe neutralize bonuses or grant 2 skills? Breath of Life 4, maybe heal all allies, or heal the user after combat?

Renewal 4, (and the renewal sacred seal) for the radioactive regeneration Alm build

I think we will get Swift Sparrow 3 soon too, with another Hone 4/Joint Hone.
And I would like to see Defiants (I'm thinking of a higher hp threshold and -1 cooldown at the start of turn if the unit is under that threshold, kinda like wrath), Boosts, ¨Pass, Obstruct, Ploys and Breath of Life getting an amelioration.

For some reason I think Smoke skills are going to get an upgrade. Something like for example: Fireflood Smoke? (Atk and Res Smoke together, with a gravity effect too?). I can definitely see Guard getting a level 4 skill. Some other skills like Swift Sparrow 3 and Mirror Strike 3 are most likely going to be things.

I’m hoping we get Darting Breath and Warding Stance 4. Also LnD 4 better be something like +7 Atk/Spd, but -7 Def/Res, my Kagero would destroy everyone.

Boost skills most certainly. A lot of meh units like Luke could use that.

I would also love some form of better pass and skills like hit n run, but locked to cavaliers

Valor Skills 4 would be awesome.
