Hunters have been the most used, and have had the highest average kds since the start of destiny. Not saying that bungies way of doing things is correct (as i dont think it is). But, that's why they nerf it, to bring all the classes as close to a 1 average as possible. To be fair, all 3 of the classes have had their fair share of nerfs. Many of the so called hunter nerfs have been shared with the others. Like the blink nerf, health regen, arc bolts, quickdraw, ect.
