Deadly Beat is one of those underrated heavies people ignore because of stronger choices (*COUGH* XMAS ULTIMATUM *COUGH*), but if used properly it could literally match any overpowered mythical heavy in a fight.
Look at the Deadly Beat = Two shot kill, slow firerate, mediocore travel time, mediocore area damage. Also a pretty high rocket jump if done properly. No one appreciates the fact we have better heavies than the stupid Destruction System and Xmas Ultimatum. Plus, its much more cheaper and easier to get!
Overall, the Deadly Beat is an underrated, powerful weapon, and so is its original variant Bass Cannon.
This is just my opinion, what do you guys think?
