I've never particularly found spies or snipers to be annoying to begin with, really. Also, as a primarily medic player, I kinda think anything that screws ubers over a bit is a good thing, on balance, so I don't really mind people having potential uber counters provided they are tricky to use. After all, we're a big asset in any sort of matchup as it is, but on pubs we're basically the hand of god and victory goes to whoever wins the halfway-decent-Medic arms race.
