Somewhat Threatening Sniper
This limit has no point of being here other than to force players who aren't fast enough to pick heavy to be forced to play a marginally weaker class than what they can do as heavy. It also encourages people to just doorhug because their contribution towards the defense would be nonexistent whether they actually defend or not. Removing the heavy limit would make the team majority heavy, which isn't a bad thing.
Also zombie heavy doesn't have a limit, and even though the zombie meta is, albeit, similar, yet more balanced (wow, who knew melees are more balanced than bullets?), it makes you able to play heavy practically at random next round if enough zombie mains played zombie heavy that it doesn't kick you off of heavy. Forcing people to play something they don't want to is not fun, especially in a game mode where majority really matters in many maps.
