It seems to me that every other soldier is somehow faster and has more rockets than me when I try to play soldier and I'm just trying to figure out what I need to do to get better at not dying so fast. I've done jump academy in the past, but I feel like I'm still a bit stuck in regards to my soldier skills (I normally main Medic, Pyro, and Scout)
Thanks in advance.
I used to main soldier when I started playing TF2 (now I go back and forth between Spy and Medic). Something to always keep in mind is your health when you're rocket jumping. Rockets do a significant amount of self damage and even if you're using the rocket jumper, even fall damage will add up and every time you encounter an enemy after a rocket jump, you will most likely be at a lower than ideal health. Playing soldier is a balancing act between using rockets to move around while also using them in battle (usually), so you also need to pay attention to how many rockets you are using so you are never caught in an awkward situation where you really need it.
Also, aim for feet. Splash damage may not be as flashy as getting a direct hit, but actually dealing damage to an enemy is a lot better than never getting kills and always respawning. As you play more and more, you'll be able to pick up on player movements and you can more easily hit direct shots.
