There is a lot of discussion about whether or not 7.3.5 will include the ability to recruit allied races, except for Dark Iron Dwarves and Zandalari Trolls.
Not adding these races in the patch would be a completely illogical choice and would be a missed opportunity to get a lot of people to level up in the new scaled leveling zones, and give players the ability to level up these new characters in time for Battle for Azeroth's release. However, the other side to all of this is sources such as Lore who states that while we're going to (and have) see data for the new races, they won't be added until BfA. Allied races are also absent on 7.3.5's Adventure Guide, which only lists ulduar timewalking, new leveling scaling, and Silithus.
I have created a graph which is listed below comparing the financial turn out of implementing the races versus not implementing them.
Clearly, the results are undeniable. There is already a thread about this, talking about speculation. This is not speculation. This is a call for help to any blizzard developer to PLEASE put some allied races into 7.3.5
Thank you.
