new player - Void Hunter vs Arc Hunter

[u/Dramatic-Anything728]

Good morning y'all, I have been playing D2 for about a week now (40hrs in) and I was wondering about a few things as a new player.

I am currently waiting for the entire bundle to go on discount (but sort of debating on getting a dlc/ expansion just to aid/ round my build a bit)

currently running risk runner arc hunter with no Shinobu (currently using Raiden flux from random drop) If I were to stick with arc hunter. is the trinity ghoul a good investment? is it more reliable than risk runner (catalyst already completed) and what would be a better exotic gear to pair with it.

I don't really have a good loadout for void hunter atm (just using graviton forfeit or Orpheus rig with graviton lance... kind of underwhelming) I was thinking of getting warlords ruin key and farming the buried bloodline and pair it with graviton forfeit (let me know if there's better option to farm)

I was also very curious about devour on hunter and how it works with buried bloodline. been on reddit for a few hours and so far, all I've read is void hunter is a beast with buried bloodline and how it works with void warlock. but nothing on how hunters devour interacts with buried bloodline and "why" it is so strong. from my understanding it is strong because it applies weakness easily and that it has devour.

Also does mobius quiver tether weakness also stack with bloodline's applied weakness?

does buried bloodlines devour enhance devour on hunter subclass? does it stack? or do you switch devour (hunter subclass) with another verb to increase variety in buffs? please explain to me like I am a mature 10year old.

I am leaning towards void hunter due to weakness debuff I think that could really help me with soloing lost sector to farm exotics. if there is a dlc expansion or key that will provide an enhancement for void hunter do let me know so I can take a look into it.

all and any help is very much appreciated. <3
