Since Class-based Tier sets are over, Blizzard should update all the old sets to Legion standards.

Basically the title tells everyone exactly what I want. I know that Tier 20 was received by some of the community as "lazy" because they probably wanted a new set, but personally I thought it was fantastic. I propose that Blizzard updates all tier sets from Vanilla-MoP (including CM sets if needed) as one final celebration for class fantasy.

In case anyone isn't aware in BfA, Blizzard is removing Tier sets and homogenizing the look of Raid sets. As far as we know there is one set for Cloth, Leather, Mail and Plate for each raid and that's it. While I sort of understand the choice and reasoning behind this shift it does make me upset. The class raid sets are iconic to World of Warcraft and gives me extra motivation to push higher tier bosses to chase that sweet look.

However, I propose that if Blizzard doesn't revert this change mid-way through BfA or for the next expansion that they update all the old tier sets to Legion standard. This would allow class fantasy to have one last time to shine before being shelved for a while. Tier 20 stayed true to Tier 6 and just completely upgraded it. For example, making the skulls on the Gronnstalker set 3D instead of being painted on.

Finally, I know that some people wouldn't want the sets to be updated. In this case Blizzard should simply add the option of toggling the new or old versions of the sets in the Options menu similar to what they already do for the older models. Or if that proves to be too complex add these new sets to the loot tables of the older raids so we need to transmog farm them. What does everyone think?

TLDR; Blizzard should update all Class sets from Vanilla-MoP to Legion/BfA standard since we aren't getting class-based tier sets anymore. Add an option so players can toggle these models on and off or add the updated models to the loot tables of old raids.
