Watch invite demos and see why they do the things they do

Don't overextend.

Put stickies where you don't want people to walk

try to mimic b4nny (good luck) will benefit you in large amounts.

play behind your medic. reload stickies. don't watch traps. never fight if teammates aren't in front of you.

Doing damage means a lot, but know when the damage is going to be useless and don't waste ammo in those situations. Avoid overextending.

Learn to aim pipes as they will save you in situations where you are being chased down.

Now to think about it, since the pope is stepping down, b4nny should take his place.

-LEARN THE STICKY CHARGE METER
-Reload sticky's over pipes (most of the time)
-Stay at medium to long range
-Aim each individual sticky and try to make every sticky do damage
-Don't be afraid to leave random sticky's on ground if it didn't hit anything and there is nothing else you have to detonate on. It could come in use in a few seconds if left there
-Don't sit on traps while your team is getting raped on flank, while you're just spamming pipes and not hitting anything
-Listen to what your team is fighting and shoot them too
-Try not to take damage on mid, let your scouts get healed

A good overall tip is learning when you should play aggressive and when you should be playing passive. Another good tip to learn, is learning how to not take a bunch of damage so you don't need to take up as much heals (Which in return, gives your scouts / soldiers more buffs.)

The number one thing you have to keep in mind with demoman is you have two primaries that do a million damage with every shot, so make the most of it. That being said, call useful damage. Try to avoid the popular "they're all raped" and "holy shit please do something" no matter how tempting it may be.

demoman dm is pretty important

if you ever have to take a 1v1 and you have the choice between using pipes and stickies, use stickies. they control the other person's movement a lot more compared to pipes, and can usually save your life if you play your cards right.

i think a majority of those 4 star posts of yours involve sucking dick

c/d

as a demoman myself, i always have to think ahead with: what if i position myself here, what would happend then and always think of the potential consequences

What RR said - if you can master pacing yourself as demo, not being too close in bad situations and not being too far away when it's time to dunk on people you'll do virtually everything you need to do as your aim and etc get better.
