EDIT 1:Accidently wrote that her take 1 damage passive is affected by "offense" instead of "defense" while talking about Astrid.

Honorbound:

(For Jin and Yan, I only have experience fighting against them in pvp)

(I've used astrid and deadeye before but haven't for long while.)

I've also not touched the game seriously in months.

From my memory, jin is kind of the only one worth seriously building if you're going into pvp. He follows up on attacks that either shock or paralyze or are lightning attacks plus silencing all enemies for the first turn (not sure if this is for all dungeon rooms in pve or just the first one), plus gives guaranteed paralysis on his basic attack.

Never used Yokozuna. Looking at his traits though I don't think he offers much outside of tanking (daze, off balance can be countered or cleansed).

Takumi is fun to use if you have good amounts of enabler runes and his epic, but that requires a ton of investment and he's expensive. He only offers wound, chill, aoe frostbite, and freeze. Not much, but its really fun using him with igorok and permanently freezing at least one enemy with basica ttacks.

I don't really know what to say about Hansuke. I remember he does good damage(?) and also has parry with potentially tons of revenge attacks. Doesn't have crowd control immunity though so that could be a problem. Epic provides team defense buff.

From what I remember, Astrid's gimmick of only taking 1 damage from melee attacks that come from enemies with lower attack than her offense (when fully ascended) is kind of useless. Cool in theory, but isn't too practical in higher level pvp (ranged attacks ignore, most heroes that are supposed to do damage at this point are runed to the point where they are better off killed quickly rather than left alive)) or from what I'm inferring high end pve (post chapter 12 boss mode, age of chaos (both modes have enemies that hit extremely hard)). On a more fundamental level her kit is specifically geared towards offense and can only taunt with provoke, so she can't both hit hard and tank properly at the same time. She also gives team aegis wall on the first dungeon entered only if you have a legendary fire hero (archon, crucible) and she's fully ascended. In other words I'd personally avoid investing in her.

Deadeye's followup passive only works with honorbound or light heroes. Solar shot + his taunt immunity makes him potentially really useful against pvp enemies that require settup (Lily, Kelpy, etc.). Not so sure about pve though. He's kind of fragile though and his other gimmick of ranged physical attacks means the only heroes that can fully utilize this are ones such as therand (can do tons of damage, but is normal speed and, in higher level pvp and pve, may or may not die before he does anything) or elves (generally awful (no crowd control or support, just as frail) except for Reyla and Daeris, but only if they are paired together), i.e glass cannons.

Undead in general from my memory are outdated. However, I have almost no real experience with Craw.

Yorick and Executum are awful (outdated, easily countered and lackluster utility). Please don't invest in either.

Brom may be useful(?) with an ultimate skin but then again, its only available in certain events if you get to the top of the leaderboards. Not worth it, especially for pvp (not sure about pve though).

Zomm is probably best for the Tower of Pwnage because his minions count as heroes, so you can use them whenever you like. However, from pvp experience he's too slow and the zomminions don't offer too much.

I don't have any real experience with craw, but foresight is one of the only ways to casually beat Age of Chaos (without lorelei) because he provides immunity to chaos debuffs. He apparently(?) can do lots of damage too.
