In order to put maximum strain on your teams relationship please equip the following weapons, I will explain why these weapons are good to make both teams mad.

1. the back scratcher/powerjack this weapon is good because you get more out of stealing health packs but take more time to heal via medigun. This will waist the medic's time and allow the enemy to get more shots on your team Then there is the powerjack. the powerjack can be used to give you a speed boost so in a race for a healthpack unless you're racing a scout you will always come out on top, although I still suggest the back scratcher because wasting a medic's time is better than stealing a healthpack. "but hahaspygobrrrr I thought this guide was about making both teams mad" Well that is where the next weapon comes in

2.The scorch ♥♥♥♥, Yes yes a crowd favorite I know but this weapon is for annoying the enemy team not only can you ignite multiple people from far away on top of that directly hitting someone with this will cause the flair to bounce upwards. and if you shot it at the perfect angle that pesron will bounce upwards too and when the flair hits the ground it deals 56 damage because of the mini crit. Annoying knockback, op damage output, stupid fire damage. what more could you ask

3. the phlogistonator. this weapon does a worse job then the other 3 items but you could make people have to wait to spawn all over again by the following three buttons, m2, w, and m1, in that order. If you play your cards right you can wipe out half their team. not only that but no airblast doesn't matter because you kind of want your team to hate you anyways

Stealing healthpacks is the one thing that will make EVERYONE hate you, 174 hp? yeah take the large health pack. medic at 50 hp? threaten to take the healthpack if he doesn't heal you.this is pretty simple

Asking medic's to heal you will make medics suffer mental pain when you have the back scratcher. You can also ask the medic to ubercharge you but then pretend you ran out of ammo. anything to make them suffer. powerjack does step 2 better but back scratcher does this step WAY better making the enemy team hate you was already discussed in step 1. now tat you have followed all the steps. everyone hates you now and congrats you are now the most hated pyro on planet earth
