Yes, because I'm fine with a lore justification for restricted classes for a few expansions. The lore works better when newly discovered races, especially those created for a single purpose, aren't instantly the same classes as we have. When they grow into it over the years of being exposed to new cultures and ideas, I like that a lot more. A tauren priest wouldn't have been as fun as the justification that they and tauren paladins are a form of Sun Druid.
I'm also okay with the restrictions for Evoker/Dracthyr because it just makes it easier and quicker for them to put out content and tbh I'd rather take something that works with some short-term restrictions over nothing at this point.
