I feel like it depends on a few factors:
1)
When you say "help" do you mean:
a. Person does everything for you.
b. You attempt to do stuff and only ask for help on things you
can't solo.
2)
Define "high tier":
a. Reisenjima armor/weapons.
b. Ambuscade armor
c. JSE, such as AF. (Which requires Omen or dyna to upgrade)
d. Escha-Ru'an Armor
e. SU 5 armor/weapons.
f. Best in slot.
3)
If No. 3 is "JSE, such as AF":
a. Do you mean to be carried through content?
b. Are requesting to join an end game LS?
4)
In terms of Weapons are you referring to:
a. Gear which can be easily soloed for you, such as Unity Concord options, but won't likely be BiS.
b. REMAs such as Aeonics.
