It's so annoying that Roadblock is now Heavy Duty though... Roadblock is the man!
It is just depressing. Just because Heavy Duty is the same kind of individual of Roadblock (heavy gunner) Hasbro is now pretending that the two are interchangeable. They aren't. The first hint that this would be done occured in DDP's Malfunction story arc where Heavy Duty showed up and machine gunned the Super-BAT. Roadblock popped out of the sewer where the Joes were and asked "What are you supposed to be, my replacement?"
After that, i think some numbskull at Hasbro though that that would be a good idea and hence the Heavy Duty switch was born. How disgusting.
I'll still probably get the comic though, at least to see if its any good.
The switch actually happened before this. When the first wave of G.I. Joe vs Cobra figures came out Hasbro made Heavy Duty a machine gunner (rather than a heavy ordinance trooper). He even came with the original Roadblock's accessories. From what I heard the figure was originally intended to be an updated look for Roadblock but Hasbro lost the rights to the Roadblock name so they decided to call him Heavy Duty. A lot of fans saw Heavy Duty as Roadblock's replacement and were angry about the whole situation. The scene in the Devil's Due book was cracking a joke about it. Later they would make an actual Roadblock figure but even then they would continue to make new Heavy Duty figures.
There was also the whokle Doubleblast thing before all of that.
Even one or two later Roadblocks had the Roadblock name but the Doubleblast bio.
