Pyro was cool after the nerfs they did way back when. Introducing the degreaser and flare gun really made it fun to play, and it did at one point take some skill to pull off (though the fire crit axe was always bullshit), the complainers frankly needed to git gud. Then just when I was really having fun with the degreaser they add stunblast…when you airblast the enemy can't move while in midair, and for a second can't even attack. That made the degreaser combos really easy to do and also complete bullshit. At that point, though, I already had my strange degreaser with parts, so I just stopped doing combos and started using it as a regular flamethrower. People who don't play Pyro say the 10% less damage didn't really matter, but it actually does matter a lot as a short-range continuous fire weapon where people will try to melee or frag you. I still did like the degreaser because you could flame one person, finish them off or dodge around them, and take potshots at other enemies in the distance quickly, without missing your chance. Even without the combos, because I didn't feel right doing them anymore, it was a cool if challenging weapon. I got a lot better at strafing. Then Tough Break changed it into a completely different weapon by substituting the damage penalty (which was good) for the airblast penalty (which just makes it more ezmode for spoiled, talentless soldier hacks), and makes you OP at full damage + speedswap for maximum cheesy combos for talentless pyro hacks with greatly diminished ability to actually support the team by putting out fires.
Direct Hit is great, I use it when I soldier and always enjoy the salty tears of Black Box faggots complaining about noskill it's not a real rocket launcher when they can't aim and need splash-heals. It's a real bitch to go up against as pyro when the enemy can aim, but it just feels sweeter when you deflect it in their face or rocket-jump off it and fry them.
Of course, I don't play competitive at all because every comp league eschews fun or intended play for maximum cheese and autistic repetition of the most efficient moves, I'm just talking about pub crawling. Everyone looks down on pubs, but a lot of teams in or training to be in comp will go all get on one side in a pub to stomp a while and build morale or whatever. Being opposed to them is fun as fuck because you already get that one kill or assist going up against three guys way better than you individually, because they get overconfident and careless. Wouldn't be worth doing with a backburner, but with a degreaser it makes you feel smug as fuck.
But anyways, when they turned degreaser into a demi-backburner and I was already using it as a normal flamer + potshots, it just got too discouraging, because I was actually using the airblast just to get distance and put people out, like a team player, not cheap combos. Too many bad decisions in a row on updates totally killed that, and also the underlying changes they made to the base game make it feel like every other shooter instead of TF2. Haven't played for months, and I was really into it for a while. If only 8ch and /tf2/ had come five years earlier.
Gun Mettle was shit. I enjoyed playing it, but it was shit because of the skins. I admit there was this one very cool skin I got for the grenade launcher which I'll use on trade servers once in a while, but I already have my stranges and skins are comparatively terrible. The contracts, though, were a lot of fun. I wish I could just play contracts, all the time, without paying or getting skins. Maybe if you finish a contract, it gives you a random weapon which could be genuine or strange at some really low chance, but instead of all the chat spam, it could just say you found that item.
Or, 500 contracts complete gives you a completely random non-strange hat. Hats were always fun.
