Long story short, this is what I would like to see:
Each chapter would contain 1 or 2 companions, for example: Northern Elsweyr: Khajiiti Necromancer; Vvardenfell: Dark Elf Warden; Summerset: High Elf Sorcerer; Greymoor: Nord something....
This would bring more customizations and choices as to what class/race you would want/like to have as your companion, and it would make them easier to get for new players (since past chapters became dlcs they are easier to buy now). Also, I think companion system maybe shouldn't be Blackwood chapter locked, but more of an addition to a chapter you already own. But whatever the case, I'd still like to see more companions from other chapters/zones.
I'd like to hear from the community and from ZOS as to if this idea is good or not, and if it could be implemented in the near future.
