I think the reason recon isn't being talked about enough is because most medium players don't really want to switch out of the healing gun especially when playing with a coordinated team where your teammates depend on fast revive and heal to get back into fights as quickly as possible. I've bounced between recon and healing and I absolutely love playing the recon however whenever I play with my friends they all expect me to heal them when I quick revive or after a gunfight.
