Minigun is underwhelming

I understand it just came out, I got up at 7am to try the new stuff out this season and as a heavy main, instantly purchased the minigun. Don't get me wrong the minigun accomplishes what it sets out to do, which is spit lead. Unfortunately as it is right now it falls into the same category as the heavy grenade launcher imo. Its a cool new player trap, seems good, can even play good, but the moment you have a slightly competent team you're facing the minigun is terrible.

I know it will most likely be slightly adjusted in the next couple of patch notes but damn you can really tell they were afraid of it when they made it, and as it is right now i can't sacrifice what little movement the heavy has to spin up my mediocre midrange exclusive sponge thrower.

Im curious for everyone elses opinions on the new guns.
