Solo Self-Found Feature

Hey,

I know in Poe 1 and 2 there a much NPC and Mechaism to gain currency or items.
Dont know if it already ingame because i had a long break.
The Suggestion:

First:

A Merchant in Solo Self Found like there Merchant Tab , just that you can Trade and Exchange with computer uniques and currency like Player Trading for for soloplayers.

Second:
a Feature for solo-players also like in Games as Dragon age and such , that you can Hire a Mercenary and equip him with gear.

Third:
In PoE and PoE2 there should diffrent Leagues or Diffculty for Diffrent type of Skilled players.
At the moment poe start smooth and gain difficulty and knowledge needs with endgames.
To make a better learning curve , Dev could make Beginner,Veteran and Master Diffculty of Leagues.

Thanks for Reading.

Good Loot.
