That's why there is a feedback forum, though I would be safe to assume that the people that actually use the forums is just only a fraction of the people that actually play the game, devs only have so much to go by. When developers see all the bashing it makes them feel less connected to the game. Look at WoW for instance, a single raid tier has over 30 nerfs combined over all bosses in a span of a month. Yet people here complaining like 1 nerf to a boss is the end of the world.
