Why does it feel like the Metal Virus arc was the only arc they really had in mind for IDW?
The Metal Sonic thing came and went
The Starline thing was built up and ended up being a wet fish since Sonic and Eggman took care of him pretty easily
The Extreme Race thing also just came and went with the only real issue being the destruction of the Restoration HQ and uh...yeah
The Mimic shit is over with
Now they're building up some "oh no someone is stealing the emeralds!" But like they also shot themselves in the foot by saying the comic will time jump to after Frontiers after 84 so...why should I get invested in an "arc" that's ending in 3 months?

Literally the Metal Virus was the only arc that felt like the comic has a story to tell and had some ramifications and even a threat of urgency for our characters.
