I agree. There are a lot of races on Azeroth that people have asked to be playable for years that would work very well and also create some hype. A lot of them either are open enough to be able to write lore to fit a situation or could use some more lore that just fleshes them out.
There are some fantasy niches that WoW still has yet to have any of, and I donāt really mind when a new race comes out to fill that void. For example, we never had any lizardmen races before Saurok in Warcraft, and creating something new like Halflings or Kender to fill that particular fantasy void when none existed before doesnāt bother me either.
Generally speaking for any MMORPG, Iām not fond of any race becoming playable being a replacement for an existing race that would work perfectly fine as a playable race. An example I use would be a race of derpy looking geckos or burly alligator men becoming playable in an expansion out of nowhere instead of getting Saurok. Sure, they would technically be lizardmen, but it wouldnāt quite be the same. If they came in place of Saurok in MoP, would I support either as I do with Saurok currently? Possibly, at least in the case of the burly alligator people, but I personally support Saurok for beingā¦well, Saurok.
Saurok do fit the theme of what I imagine lizardmen to be. They have an interesting backstory and are awesome in general. Iād be disappointed if some other lizardmen race was created for a specific expansion that got to be playable over them. There are exceptions, of course. Something like Sethrak that are reptilian but a different species works great as a playable race and would be a great contrast to Saurok, especially if they were put on Alliance and Saurok on the Horde but would still complement Saurok if they were both on the Horde. In this case, I donāt see one ever being a replacement for the other since they offer different things.
With regards to the four covenant factions, Iām still not entirely convinced they would end up as allied races, even with the datamined discovery. Even though we donāt know them well, I feel like theyāre stuck in the afterlife world and would remain there storyline-wise after we move on to the expansion after Shadowlands. I have a hard time seeing them just being able to enter the living world of Azeroth at all. That said, I have no issue with those that want them (we all have races we want playable). I just need to see something more concrete before I can give more of an opinion.
Anyway, in terms of playable lizardmen, itās Saurok or bust for me. Their backstory would fit them as members of the Horde just fine, and if given some love in the storyline department, Iām sure there would be some awesome gameplay moments if they were given the chance.
