im not a tent main, but i do have some experience playing it & learning how to fight it
tent's most important job, and the thing it does best, is staying alive. When you're playing aggressively, try to put yourself in positions where you can attract the attention and resources of the other team without immediately dying.
Approaching from off-angles is generally the best way to do this because it forces the enemy team to split their attention between your teammates and your shield.
If you ever find yourself in a situation where you think you're going to die, keep in mind that jumping out to teammates, beakons, or even back to spawn is always an option.
If you can't find a good opening for an off-angle, you can still stick around the rest of your team and shoot your tent toward the enemies to keep up the pressure & paint.
These r just generalizations of tent's playstyle but i hope it can help you improve :) GL in your tent endeavors!
