As you probably already know, I'm with you on this.
I'd love to nerf BAR to having only the advantage of damage, and lower the fire rate.
I'd also love to have the souizen's fire rate nerfed, and leave it with the advantage of low freeze.
If it weren't for the potential player complaints, this would have been done back in August.
I encourage you to start a petition, poll, or something that gives backbone to the idea of nerfing the OP guns. I'll even sign it myself, or vote in favor of it.
But I won't do it without sufficient support. That would only cause me to go the route of Cloyd, and get fired for trying to add more emphasis on skill.
Frankly, I don't care if somebody paid $100 for a gun. I care about a player of lesser skill overpowering a skilled player just because he's got money to blow. This should never happen.
