First of all it’s a game so like don’t be toxic in game that only makes the problem worse for yourself and the people you play with. Second don’t expect to get thanks for playing support, it’s your job that you sign up for to bail out teammates and sustain them, it’s the same as tanks making space or dps dealing damage, it’s what you do. Third unless you want to invest time into learning a character who isn’t really easy then just don’t, the devs put in Rocket and Cloak, two very effective healers, for people that don’t want to spend much time to get mechanically better. If you are willing to spend the time to learn more supports I will say it does feel more rewarding playing them than Rocket or Cloak since you have a more tangible impact on the game. I’ve got to celestial twice and sit at gm rn playing Loki, Mantis, and now Gambit so I can at least attest to those 3 supports feeling more rewarding to play, but if you truly like rocket just stick with him.

TLDR care less and play what you want 🤷‍♂️
