So, with recent screenshots of Uldir, a titan facility that apparently uses the same architecture as most Troll temples, and concept art circulating of a "Mayincatec" looking Titan Keeper, I'm concerned Blizz is going to turn the Zandalari into "Mogu 2.0" (3.0 if you count Highmaul era Ogres)
I feel this would be a bad decision, one of the most appealing aspects of the Trolls is that they're a natural/evolved species, and the Mayincatec style of their buildings is one of their defining traits, it feels pretty... lame, for them to have just copied it from the titans.
I'd much prefer Blizz keep Trolls a naturally evolved race, and make it so that the Zandalari built 'atop' Uldir to reinforce the locks keeping G'huun, rather than making them another monstrous race that worshiped a boring human-looking titan keeper. Especially after how poorly the Uldum keepers were handled.
