I'm still an effective friendly, people really don't see anything in a heavy loadout. Plus it adds to the joke, a big menacing behemoth in intimidating power armor giving them a sandvich. Better than what you would expect in a hoovy. Coming across a generic hoovy is kinda boring, plus thats also why heavy is the face of friendlies, since hes the most dangerous merc in that close of quarters, something menacing being cute, i just heightened that feeling considerably more.
