Last Epoch

I've played a fair few builds but not very far, I usually clear the first 3-4 timelines and then check another char out, game does have good variety of builds although balancing wise there's some pretty extensive gaps between the top tier stuff and the rest(and then the completely broken shit like falconer builds).

List of the stuff I've tried:

Wolf beastmaster(plan was to go squirrel later), good single target, good survivability, meh map clear cause of no real aoe and wolves mostly tunelling the same target. Feels more like a melee build than a pet build too, like a pretty standard poe strike melee with leap slam > drop totem > buff up and spam really fast attacks with really shit range, wolves do a lot of the dmg but they're just kinda there.

Fissure warlock, good everything very strong and very easy to play just run around dropping fissures and spirit plague as stuff just kinda dies. Definitely felt overtuned as it has no real weakness besides maybe mana a bit but even that is easily fixed, it generates tons of ward for free, has tons of ways to scale damage and does full screen clears but also very high single target

Poison pet necro, focused on skeleton rogues and melee wraiths with all poison stuff, very high single target(I think my highest for consistent dmg) but pretty meh map clear, pet AI isn't great and since it's melee minions it has more issues, rogues do help with shurikens and acid flasks but it's still not great especially since it's pretty reliant on dread shade to do max dmg so even when they split they don't kill that well. Low survivability too since no real defenses other than pets(although with bone golem that's fine and later on low life ward shenanigans with decay aura for heals+additional poison scaling instead of golem).

Shadow daggers Bladedancer, good at everything and very fast, fun to play. Bit squishy if you get caught but can probably fix with better gear and I had a lot of defensive passives to take still as I took a lot of dmg first. Shadow daggers scaling is stupid. Very fun to play overall and felt basically perfect for the quick rogue type char, you're constantly moving super fast and you have ridiculous burst, definitely nailed the design, although I think the skills should do more dmg and shadow daggers less

Decay aura+wandering spirits poison Lich, this one was a bit of a disappointment, I know it'll scale great eventually but the leveling was pretty horrible. It takes way too long to get the generic leech nodes in Lich passives(they're all the way to the end) so you're pretty fucking squishy, and aura of decay obviously hurts you so that doesn't help much. Reaper form means you have a cheat death built in pretty much and it did work ok with Life Drain but takes way too long to get online. I've seen videos of it being played though and the map clear looked excelent and the single target is pretty good too, while being very tanky, but it's likely better to level up to 70 as a normal nuke lich then spec into poison lich stuff.

Ignite explosions fire spam Sorc, good map clear, average single target(unless fighting a big boss where you can get all novas hitting), pretty fun to play but on some map tiles lags like a motherfucker with all the explosions. Uses Frost claw with repeated casts to proc tons of big overlapping Fire Novas all over the screen to stack a lot of ignites. Teleport+Meteor combo to regen mana and get strong defensive and offensive buffs. Very tanky too since it burns through a lot of mana for mana > ward affix and just generate good ward+has a lot of ward retention+Flame Ward for on demand big bursts. Only downside is you use Teleport almost on cooldown for the buffs and to cast Meteor for free for the buff from that, which mean boss mechanics have to be planned for(either facetank with high ward, run normally or hold teleport which can make it a bitch with mana regen).

Have yet to check the warrior guy, I think I'd like a pseudo pet build with the animated weapons/armor shit but it looks like it has the same issues as beastmaster(maybe even worse) where it's stupid single target but pretty poor map clear. Don't care for the other 2 design so eh. I think I'll check out Spellblade or Druid next.

That helm goes "slightly" past powerful, it's super broken. Even used normally it's already quite strong but you can do some shenanigans with mass summoning stuff and it'll consume everything and then one shot T4 julra and shit. I assume they'll nerf it a bunch(although part of the issue is bone curse walls counting as minions which basically gives you 12 "minions" to consume in one cast) but thematically it's really cool and even without stupid stuff it's still very strong.
