As the title says, why? All of the Decepticons (bar Dreadwing for obvious reasons) were better developed and appeared a lot more before Megatron came back. For example, Soundwave and Starscream. Two characters with enormous potential that slowly degraded after Megatron returned. Starscream hasn't done anything that has lasted, except finding the Harbinger again. Soundwave has given us two of the most insanely awesome moments of the show, but that's two moments in 30+ episodes. Both did a hell of a lot more before Out of His Head. So can someone explain why, and give your thoughts on the matter?
