Most useless class?
What is the most useless class?
I'd say recon.
Because post 30, your sniper is pretty much pointless as people are all over the place, but your bullets are slow as molasses making it pure luck/spam that you would ever hit anyone with a sniper, even then its a 3 hit. Bombing would be good, if your bombs weren't easily dodged then your useless for 30seconds, shatterbombs only catch people who aren't looking, which is pretty hard to not notice. Meleecon is sooooo bad its not even funny lulz.
Recons are just fodder and anti-turret helpers.
Recons jobs are to snipe turrets and medics. Just because you're bad doesn't mean the class is useless. If you have less than 15 bot kills in a match then you should go robo since you suck.
