Just when I had given up on the Devs for missing frankly a golden opportunity to add a bucket load of new and highly desired customization to the races while making the new models through sub races, they reveal (although in played down language) they're working on sub-races.
Okay they're thinking about this - is like when blizzard say soon. It's been in the pipeworks, and they haven't sorted out how yet, including the:The team has talked about more customization, such as sub races, for a long time. Some would require different models with different textures. A good way to give players access to the different races would also be required. Perks for the different sub races might also be interesting.
Question of how are they going to introduce them? Once out should they:
1. Have different class selections to the main race
2. Have different racials to the main race.
3. Have separate introductory narrative.
4. Make the effort to give them different emotes or:
5. Just slightly change the emotes of a main race. e.g. San'layan will not say "For the Glory of Quel'thalas"
6. Give them their own starting zone i.e. a level 1-6 or 1-12 phased version of their zone OR
7. Just let them start as advanced races in the level zones you meet them in game e,g, Dragonmaw at level 84s Twilight highlands. with one quest too show the hero is going to fight for the horde/alliance from then on if they don't already have that quest OR
8. Just let them start with the main race in their starting zones, no need to trouble with phased zones
There is no better time to add the extra customizations to make sub-races than when you're working on the actual new models. It's better than going back and fiddling with the models at a later date to change stuff, re-hire voice actors etc etc, the time to do it is when you're doing the main race model. And the majority are really easy to do compared to the work of designing a new race since they're just adding to the new model they've just done.
Some sub-races require very little extra work; e.g. Mag'har orc is just skin tone customization granting different shades of brown, same with dragonmaw - which grants different shades of black. Some are more work, like Taunka - which would require different face animations (not body), because their faces are different to Tauren. Some a lot more work like Broken, which would have to be based off a different model, require different voice emotes.
I have no idea how far they would go, but how far would you like them to go?
