My preffered strategy as demo.
1. sticky carpet.
2. spam from safe place at enemies.
of course it only works on defense, I suck solo.
I think my most used classes are demo, soldier, and Pyro, but I'm not to good at any of them.
bottle is amazing versus noob spies

.
by impatience, I mean: as heavy, I walk around corners not spun up; as soldier, I spam.
By the way, today, tragedy struck!
Okay, I was over at my friend's house playing Tf2 on the Xbox (The only version I own) when my friend's retarded brother pulls on the ethernet cable and the Xbox falls over! Suddenly, the screen goes blank and the Xbox starts making bad grating noises! My friends pulls out the disc, and there's a deep, circular scratch running the entire way around the disc...
I put it back in the Xbox. It didn't work...
WHY, GOD WHY?!?!?!!!!
It's okay though, my friend's mom is buying a new one

.
okay, back on track.
the three leading classes in the "Axel's favorite class" tournament are the Demo, Soldier, and Pyro
Demo: I don't use nades. If I'm going to learn to predict in my aiming, the soldier just there better choice. so i use the stickies, either laying traps in choke points, as sticky carpets, under a distracted enemy, or leading an enemy in to them. if I hem an enemy into a room or enclosed area, I usually spam nades in/at them. This allows me to kill an enemy before they have a chance to retaliate, with the first blow. However, with this play style, I must cover all possible routes that allow the enemy to charge me, as I not a proficient nader. This is sometimes impossible.
Soldier: when I need things done that a single class can't handle, I use the soldier. The soldier combines the demoman's high damage, splash damage, and long range suppressive abilities, with the pyro's dangerous close combat abilities and versatility. Charging Pyro? no prob. sentry? said and done. However, my rocket prediction is abysmal anything beyond 12 ft. This would be manageable if he didn't have four rockets in a clip and dead retarded reloading speed. This means if your first two rockets don't land, your screwed. This also makes me the world's worst soldier. I once ambushed an engie who had no sentry or teammates. I lost. That doesn't mean getting good is impossible, as occasionally I will gain proficient skill. This took a lot of time though. a lot of time.
Pyro: The Pyro is often been my favorite class, as his normal health, normal speed, and his shotty mean he is the most balanced class in the game. coupled with the ability to not aim, flame retardant suit, and high damage capabilities creates an easy used, versatile fighter, and as such has been my best and favorite class more than a few times. However, his close-combat weapons means the Pyro must put his neck on the line in order to do decent damage. Lacking a explosive weapon, this makes attacking a group bigger than two people or a sentry is a suicide mission. It is possible to get enough skill to survive these suicide missions, but there's only so much a Pyro can do. This means for all of the Pyro's versatility and skills, in half of the million most likely combat situations, He can't do lick shit.
so, what should I do fellow forumers?

Thanks, once I get enough time I'll start on that thread.
