It's true that, in Guild Wars 2, there's no such thing as a dedicated "support class". But it's also true that a player can individually try to "support" in specific encounters, and the game doesn't do enough to reward that. This isn't specific to World vs. World, either. "Supporting", in the more literal and moment-to-moment sense of the word, is possible in GW2, and it's much more dynamic than the current trope of pigeon-holing "support" into dedicated character classes whose job it is to heal players and use crowd control on enemies.
