Yes, now cross faction play is here and expanding to guilds too, and we can make up our own fantasies, I wonder if they'll add some more official cross faction inter play or at least make it interesting in the story.
Keeping the faction identity and conflict, but also making provision in the story for races and groups that can get along could be very interesting and I wonder if they'll pursue this further now. officially there is very little support in the lore, the factions pretty much hate each other (by developer design) and barely stand each other when cooperating.
This is very unrealistic, especially after so many battles fought together, and though there is enough betrayal and grievous wrongs to make it plausible enough, there are many areas where there isn't and also some instances where we know races across both factions have deeper connections. I would like to see these explored.
1. Forsaken and human
2. Blood elf and Draenei
3. Lightforged with Blood elf and Nightborne
4. Druidic tauren and night elves
5. Blood elf and human
6. Void elf and blood elf
7. Orc and human (via Jaina and Thrall and those who fought with them)
8. Night elf and Nightborne all that history (not forgetting Farodin, Farondis and the Val'Sharah/Suramar night elves in 7.0
9. Mechagnomes and Goblins
Frankly every race has reason to hate, but also reasons can be found to cooperate, in fact you can also have factions within a race that actually want to work with a race or more from the opposite faction and those who just want to kill them. Similarly, not everyone within a faction likes each other.
this nuance would be nicely explored
Some great new ones could form.
10. Worgen and Troll I'd love to see
11. Nightborne and Draenei
12. Nightborne and human
13. Worgen and Tauren
14. Orc and Draenei - yeh, they're supposed to really hate each other, but I think it would be fascinating to see some strong bonds develop amongst some key characters.
15. Dark Irons and Mag'har orcs
16. Mag'har orcs and Void elves
So far, blizzard has always emphasised the hatred, to stoke up the faction aggression and hate - ofc this has had a negative impact on the community, the balance was never sought as the corporations were often either muted, or never followed up well. We should have had both. Would be nice to see some occur. Which would you like to see?
