When leveling I use EMA to auto trade greens between characters, and I use a mod called "autogear". I FFA loot, and my main character loots everything. Then when I'm full, I trade everything to toon 2. Toon 2 runs an autogear scan, equips anything that's an upgrade, then toon 2 trades to 3, so on and so forth. Makes it pretty quick to sort through gear upgrades without having to fiddle. In the end, everything gets mailed back to the banker type character, be that a special banker, or say your "main" character.

Autogear isn't ideal, and it might be replaceable now that Pawn is working for classic. However, if you do use autogear, you can go in and change statweights. For example, autogear by default weighs str like 10x higher than anything else on dps warriors. Which is problematic when it wants to replace an 10str 10 stam piece with an 11 str 9 int piece. So, I edited the weights in the lua file to give stamina enough weight that str stam gear would be favored over str+anything gear.
