why are you doing +4 anyways
all the good gear is in argus
gear through argus then progress to mythic +6+7+8+9+10 ect
argus treasures, rares, world quests takes roughly 2-5 hours to finish per day
650-1300+ estimate of veiled argunite
get 2 gear items everyday up full 910 item level in 2 weeks
after 2 weeks you get 1-3 per week over 910 items to gear with
mythic 5 or lower is dead and only done to level the keystone if you started from scratch
