I play a Scout and am rather vocal about it, you’re still new so I understand if you weren’t aware. I have a hard time remembering what people have said they main too.
The scout speed + Double Time is the only advantage they have, you’re not wrong that it’s the trade off for their crappy health. Most people don’t also consider that they can’t carry the same number of gear or perks that the Recon can, you get serettes and something not worth taking, joy. (Haven’t played much with the new stuff because I cannot afford it gear wise, that still pisses me off.)
The patch they upped the double time is also the first time I’ve actually felt faster than the other classes, before they’d be right on my ass, now I can actually get to the objective first and make sure the alarms don’t go off. I’d really rather if people didn’t get it nerfed because they can’t figure out to jump over things and use obstacles.
