There's absolutely nothing stopping them from making the Sylvanas weapon token give that bow for hunters. Just because Castle Narnia gave covenant themed weapons doesn't mean tokens == covenant/generic weapons.

It's always the same classes getting the high ilevel weapons as well. If they at least rotated it a bit each time, I could maybe accept it even if it's still stupid when there's a better alternative. But if it's always the same classes, that's bullshit and they should just do tokens instead.
