You’re totally right. The Horde questing experience should involve planting trees in Ashenvale as well as picking up garbage on the shores in Azshara and removing the Horde symbol from the landscape.
We, as players, should suffer and pay community service to the purple hippies because of the choices made by the writers of a video game.
Nobody. Not even the most loyal of Sylvanas fanbois deserves to be punished or even mildly inconvenienced in order to in some way atone for the choices made by the writing staff of a vidya game.
