I also didn't say the ambassador was better all the time
This whole argument started literally based on what I bolded.
You must not know the definition of a crutch in games, the liberty launcher is an actual crutch, it's rockets travel faster but has less damage overall, and really has no use to an experienced soldier (of which there are PLENTY) because it's only arguable upside is being able to hit for example, scouts which an experienced soldier can hit.
The Ambassador requires an inhuman amount of skill to be considered "better" because unless you never miss, the revolver out damages it which a very good amount of players lack.
It's not nearly as difficult to body shot people a close range making it overall more effective for almost all players.
Just like the Bazaar Bargain is the best sniper in the sense that if you never miss a headshot you'll be rewarded.
But even the best Snipers I've encountered STILL don't use this and use stock.
