Good for you, you’re wrong.
It is the purpose and location and function and design. Cities and faction locations often times have several NPCs, they are attached to a specific faction (Horde, Alliance, Goblin), multiple different vendors, their location and proximity to certain areas and the level ranges of those areas matters, they generally have flight paths, they are meant as a central hub for players to gear up for their next adventure. None of that applies to incursions.
Uh huh. Except that it is VERY different than both those areas. The Rebel Camp in STV is a faction specific location, being Alliance. Also there are no guards there. The guards do not attack people. You can be ganked and camped there. So what exactly is this comparison? Also for Moonglade, it is a druid centric training hub for a class that encompasses all ranges and level and is meant for their class training. The game requires the classes to go there. Incursions are optional content not class focused content. And don’t give me that bologna of “BuT iT’s To StRoNg To Be OpTiOnAl” that’s not an argument.
But consequently not in Classic. Which SoD is based on. Also Un’Goro is a Cartel themed faction and has a flight path.
Not in this case. Because:
