LMGs are melt-machines, I almost feel dirty using one, particularly if paired with the TF.
Nothing worse than someone sitting in Top Warehouse/Grandmas/Yellow on Standoff with a TF LMG. Anyone who believes that gun requires more skill than a sniper is deluded.
And there are many ways to deal with it too. Use cold blooded. Toss an emp before going around the corner into sight. Toss a smoke to cover movement. So not really an issue. So a TF-LMG is not really that hard to kill.
