That IS true. Other than Dreadwing killing Seaspray offscreen, he did failed a lot. Fail to destroy Airachnid, failed to retreive Breakdown's remains, failed to retreive both Apex Armor and the Omega Key.
Starscream's track record's not that good either, but then again obtaining all four Omega Keys is kinda a big accomplishment there. I guess Megatron in the end, was impressed with Starscream's accomplishment given he had limited resources, with the absence of his T Cog, he still managed to make use of those limited resources to the fullest, and obtained the four keys. Picture what Starscream could accomplish with the resources of the Decepticon army.
Still, kinda harsh decision being made to kill Dreadwing. With Breakdown dead, and Airachnid going rogue and in stasis, Dreadwing is the only competent fighter left(other than Soundwave). Knockout and Starscream, are not quite competent, not that they're not strong, they're just not dedicated enough to finish a fight and might retreat from battle when things goes south.
