I've been testing around with different skills and such, also made a post here a couple days ago asking for advice, and I think I've found my leaguestarter:

I threw this together in the past hour or so. I think I've solved most issues, there shouldn't be any left. There are quite a few upgrades to get to increase especially phys max hit and overall dmg. Look at the notes section for more info. Feel free to criticise, aka to roast the pob and point out mistakes I made that I missed. Or just tell me your general opinion of this (this is pretty much my first cold dot build ever).
Cost for this setup should be about 100c I think? All uniques are cheap early and only chaos res gear makes me a tiny bit worried, but it'll be fine. I just won't go LL before Saffel's and chaos res cap, if I do that at all that is. Cost starts rising once I try to get gem levels, corrupted gear, 6l and such.
Made for pushing ~lvl 80 quick and then go into logbooks and heist contracts. Not made for red maps, can't guarantee it'll work there, haven't tested it, maybe just test it yourself.
I personally dislike Rolling Magma playstyle so I'll be swapping to Wintertide Brand before Merveil (use it alongside HFT and FW until Runebinder, around end of a2). Tested this in SSF a few times now, not the best but it works.
For later progression I will swap into Storm Brand of Indecision or maybe Penance Brand of Dissipation in case it's not nerfed too hard.
(Tiny explanation as to why Wintertide Trickster: I chose Trickster because I like the defenses in endgame a lot and it can stack a lot of movespeed, dot because it's very useful for expedition mobs, brands because I like the playstyle and it lets me use the chest open mastery, which is very useful in logbooks).
Ofc all of this has to be taken with a grain of salt, patchnotes are always wholly unpredictable and might change all of my plans. We'll see tomorrow.
