I noticed with the companions they leave a lot to be desired so I've come up with a few ideas and suggestions that I would like to see.
1. Companions settings
Give the player the options to set the companion to only do DPS, Tank, Heal or a mixture. Personally I've had multiple problems with this when needing my companion to only heal me and I die because he is focused on another mob instead of healing me.
2. Companion Target
I want to be able to always see what my companion is targeting. I like to make sure my companion is attacking/targeting who or what I want.
3. Attack Same Target
Not much to say about this one but that I feel like its a must.
