Additional Notes
Well, if I do happen to join your team in whatever server I choose to join, I would heavily consider myself a Defense specialist. I happen to be great at the Counterspy, Flag Guard Sentinel, and General Assist roles, and if I really want to have some crazy fun, I'd go Field Intercept as well.
Because the enemy team spy-checks as a standard, O would be a lot harder than D in many cases. Until needed improvements are made, the spy has the best chance be good at Flag Running and General O Assist. It's silly that teammates have to shoot each other incessantly in those TD off servers.
But then, I hear others who loathe, mock, and none-the-less frown upon D spies, as they automatically assume spies are not well-suited for D. Let me tell you this: it takes a lot of SKILL and NERVE to handle D roles. You get the biggest piece of the action pie, and you gotta be able to eat it all. A well-skilled D spy vet can save the team a lot of headache as more and more enemies suffer flag run failures, often with a single tranq dart followed by a single shotgun blast or flurry of nails.
In short, as far as D goes, the spy can be the biggest asshat you'll ever know. And that's a compliment, considering that the spy's team is the one winning
