I'd say I was a bit of a self proclaimed boss in tanks as well, I freakin' love the T95. I'd say it would be considered a noob tactic to just whore the tanks and never venture anywhere on foot, but I personally don't care. I don't understand people saying stuff is a nooby thing to do because it bags you easy kills.
If it kills people, use it!
The only exception is using frag rounds in auto shotguns. You're just a gigantic cucking funt if you do that, especially if you're one of those people that have it as their dog tags and boast about having a million kills with it...
