First of all, I'd like to say hi, thanks for running all these awesome team fortress servers, all in my favourites.
That out of the way, I play mostly spy, and seeing as how many of the people I see on your servers I end up playing with a bit, and they seem quite good, I was hoping for some tips. I have most basics down, map knowledge, where the ammo boxes are(I use standard Invisibility watch alot, and Cloak and Dagger), how to stab engies and sap their sentries without dieing, telefragging, etc. Just some general knowledge and tips to improve my game.
Also one question, I was playing spy earlier today on badlands cp, and one of my team mates was getting up me for disguising as a friendly pyro. I use the friendly disguises while amongst my team and to cross ground where an enemy isn't likely to be(ie: heading away from my team). I then promptly cloak, change disguise, get behind them and attempt to get a few kills and saps. Is this not the intended use of the friendly disguise or am I doing something wrong? (I also try and use it in arena, to lure enemies around corners thinking they are up against a weak in combat class before stabbing). I just hate seeing "teammates" walking amongst the other team, or even worse, inside/outside the spawn area during setup. Thanks for all your help.
