No, i'm not going to be happy if i have to be a sniper on one of those closed-space maps because everyone has already filled the other classes. Just putting it on scouts is fine, nobody wants to watch a scout run around and do crap damage because they cant escape saxton another way.
This game is about teamwork to take saxton down, scouts don't contribute except for distracting, even then they do a terrible job of it.
The limits WERE for heavy, sniper, scout, engi. The other classes were unlim.
Now it's only scouts (4) that are limited.
