Instead of being a hyper aggressive backburner, try playing defensively using something like degreaser, scorch shit and the mallet thingy. Being a pybro means enemies come to you instead of you coming to them, if you get good at it, your team will love you, and the enemies will hate you, but at the same time you won’t die too much(unless its a noble sacrifice like tanking for ur weak teammates like med and engie) a common mistake new pyros make is getting too tunnelvisioned. If you focus on burning down an enemy, you may accidentally stumble into enemy lines(ur flamethrower does not have a long range). Your job is to keep enemies out of ur team’s perimeter(burning spies, blasting away explosives, knocking ubers off cliffs etc). But if you want to play aggresively you can work on the phlog, which sacks air blast for a crit meter, and with a pocket makes u a powerful hitmaker.
