Questions I didnt find answer in Ative Help

1. If you did not yet unlock the aesthetician, you need to find the NPC Jandelaine in Limsa Lominsa to unlock this feature.

2. Here's a reddit thread I found on google.

3. You can roll Need if your current job is able to equip that piece of loot, if not you can roll greed or pass. Need rolls take priority over greed rolls. Some items, like mounts or minions everyone can roll need on them regardless of what your current job is. The most current raids have weekly restrictions on loot, so once you obtain a piece of loot you have to wait until the weekly reset (tuesday) to be able to roll on loot from those instances again.

4. 2 retainers is the maximum you're allowed to have. You can purchase more from the mog station, however, at a cost of $2/month/retainer up to a max of 8.

5. This is hard to answer as most everything in the game has some kind of purpose, you should confirm what the purpose of the item is before you decide if it has any value to you or not. Here's a resource you can use to help answer these questions.
