@sighyThe Zandalari were completely ruined by BfA, and troll lore suffered greatly. Specifically, in MoP you could correctly say the hostiles were acting under Zul, a traitor in the making, rather than representing the Empire. BfA destroyed that and made them into nameless faction goons because "troll models without back problems". Troll fans often and rightly decry how trolls are mainly used as dungeon and raid fodder for any development, where the original Zandalari showed they could be more. A large part of what originally made Warcraft interesting was the willingness to break from cliches, like evil orcs and trolls.
Now, instead of a aloof race of wise trolls, we get more "rawr me Horde, me have grievance that will NEVER be addressed" crap.
