Portals while yes exact timings etc might be something you dont know right away roughly knowing how they work is kinda how you would expect it Dark And Darker Gold.
as time goes on they spawn in the Ring (also the when how and why is Litteraly just time not much to understand there and i think thats also litteraly written in the fapdoodle thingy)
As for having to learn the map from third party sources I might know the occasional room but have a overall very bad understanding of the maps since i dont bother to much and still run high all the dungeons relatively succesfull (also mostly playing in a duo when i go to the "3 man queue" so its not me just being carryied all the time.
you do litteraly have a minimap (though on goblin caves it does need work since its bad at displaying different floors)
and no need to actualy know the map since unlike tarkov you dont need to know Location x is 10 minutes walk to the southwest with the switch locatet at y and then i need to use this and that item instead you see a big circle and alright thats the area i gotta stay inside (if you wanna be safe try to be around the middle area)
My first run On goblin caves funnylie eneught was me Panik running trought 4 or 5 rooms before dying to spikes since i had no idea yet how to fight goblins (took me until roughly the 3rd run to be confident at that) and well as mentioned i mostly play Wizard.
So you definitely can bypass enemys even as a Wizard (i would even say he is quite good at it since you can Litteraly build 3.5 seconds of a Lead a couple times before needing to have a safe spot so thats a easy door opening not to mention you are just faster then them already)
I mean Wizard In theory would work without meditate but thats extremly restrictive (basicaly cant do any pve or you are at a snails pace) and is probably more of a meme or Full on pvp build for premades so yep 100% agree that in terms of the skills you can choose Wizard has not realy any options but he kinda is the only class where that applies so 1 Class having very little choice in terms of their skills being = some classes have no Customisation or Creativitie Realy is overkill.
Especialy since Wizards do still have a Couple different builds they can go for as well as one of the things they are locked into opening up a bunch of new choices Dark And Darker Gold for sale.
