God khola that avatar's driving me nuts considering I'm in dubai with no access to drugs of any sort :S not cool lol

Demoman advice - when in doubt spam nades. When not in doubt spam nades. When fighting scouts or Pyro's Be more accurate, coz your dead whatever happens.

Unless your me.

Pyros don't have a chance against demos unless they manage to get behind you and/or your aim is totally crap and you can't hit a slow moving target 2 meters away from you

Scouts on the other hand are nasty little buggers to hit, but when you instagib one the satisfaction can only be explained with

Even more satisfying is when you see Bolt's name in the top right corner .

I dunno depending on the situation a pyro will kill you as all he has to do is hold them flames on you for a second and you die even at full reach as they do a ridiculous amount of damage, also depends on how good the pyro is whether or not he throws in a bit of 'a' and 'd' to make he harder to hit aswell as the 'w' and mouse1

ANd scouts hardly ever instagib, ive hit 3 nades on a scout and had him still kill me due to random damage

I don't instagib from nades too often. I'd say about a 1/3 of the time. Stickies get me more often. Do they have any dropoff at all?

I find it's best to weapon heckle demos from mid range into using stickies then rushing in and meatshotting em.

No, neither nades nor stickies do have falloff.

Id probaly say 1 in 5 nades are instagibs and well as a demo its not really kill the scout but more run off and cover your tracks with stickies chances are you wont be able to kill him

Pyro's are Easy to kill IF they are in front of you and not close enough to flame you/hurt you from the splashbac of your nades. Scouts - Blimy they are hard to hit, but with good enough accuracy, and a bit of Welsh-Scythe-farm magic then they are merely gibs for you to play with. If a pyro sneaks up on you from behind than your dead whatever happens, at that range any nades will kill you as well... but by all means use then 'cause they will damage the pyro as well.

Accuracy is less a factor when hitting scouts, it's prediction aim. I find scouts easier to hit because I make a habit of targetting scouts so I've got a better feel for the range (i.e. putting the nade where the scout is going to be). With pyro's they're fast over the ground and a good pyro strafing all over the place gives me no end of problems, as by the time you've planted a sticky to cover your retreat, you're already on fire.

The answer is the same as any other scenario I suppose, practice makes perfect.
