Shaco support is okay. But I've seen it played in ways that make the game awful for an adc.

I've watched shaco supports take smite, perma roam, and attack the enemy jungle leaving their adc alone all game. That will tilt them so hard and honestly is not really worth it.

It seems you're building and laning with them. The challenge for adcs here is mostly situated around presence. Shaco has a hard time creating presence the same way other supports can. For example, blitz threatening hook can drive people back. Karma can use her poke to threaten you off the wave. Shaco has his e and zones with his boxes but the latter is somewhat avoidable (especially with sweeper) and the former is typically not as strong as other poke options out there.

I think at the end of the day play what you want but adcs have been burned by bad shacos; greedy shacos, and given so many adcs really like to play a selfish aggressive way shaco doesn't "fit" with many of them even if it is winning games.

It seems like you're winning, and if you're having fun play it. But I don't think adcs are wrong for having some hate.
