I'm grateful to not be limited to only rocket launchers for heavy weaponry, but I feel a little bored with having only one alternative for my heavy weapon type. So I'm suggesting the addition of a third heavy weapon type. I don't even really care what it ends up being, but if it actually helps I would suggest creating a Destiny take on the railgun. I'm sure Bungie could come up with some great ideas for heavy weapons, though. I just want to experience them.
