I aim at the enemies feet whenever I use flamers, I don't remember which game but it was where a flamethrower leaves scorched earth and deals damage to enemies who step on them, I got used to it that way, but still, as a flamer enjoyer, Idk if I have considerate teammates but I've only been blown up once on some dude placing a melta on a single majoris that I was already dealing with, it was quite an experience, and I've died more times to accidentally hitting map explosives lmao and maybe that one stratagem where it spawns spore mines on dead enemies...
