Rarity will only help if your maps have decent mods on them. Make sure you've got some tablets and upgrade your atlas passives as you go.
I would watch some videos on how to juice maps, without making them too difficult for the gear you have.
Deadeye is typically squishy so dying is common. Don't feel bad unless you're juiced to the tits with insane gear.
Make sure you have some chaos res too if you don't. Boots and belts are a decent way to get resistances if you're not running uniques.
juicing is quite simple, but you must check how much you can handle:
do grand mirrors and prepar maps to get 200% deliit should give you 50% more quant -> moobs get stronger
on mapsyou want t15 8mods
sth like rarity/effectivness mixed up ~50++ combined
extra monster rarity and pack size if possible
tablets
prefixes:
rarity %
effectivness%
after that best mods as earlier monster rarity and pack sieze
on suffixes for tablets choose mechanic you wan to farm to get as many rares as possible:
on abysses %to get extra abysses and +rare mosnters in pits
on breach also extra rare monsters
if you want farm deli pack size of deli monsters
if you manage to clear those you can add up rewards/level of difficulty running 4tablets on city maps, later start using +2extra random mods on map (suffix) but for that i guess you must have thousands divs invested minimum to handle those maps
appreciate the reply guys! ive been watching some stuff i will have to make sure to keep an eye on the rolls on maps ive just been juicing them blindly half the time
