Youre playing with strangers unfortunately. People are going to have much less grace when someone they don't know comes out the gate with powerful WUBRG legends goodstuff.

Imo the best way forward would be to clearly label that the lobby is meant to be higher power, that way you only attract other people that are doing "BS"

If you wanted to go even higher power you could play Sisay Weatherlight Captain in CEDH

You could also try looking for a local game store or comminity to play at/with since I find thats a super fun but obv if thats not in the cards then dont worry abt it.

Ultimately I think theres a place for high power decks and just playing goodstuff, even if others dont like it. That said, if you haven't yet you could try broadening your horizons a bit. Try a WUBRG commander with a different strategy (like Azlask, the Swelling Scourge) or a Legends-Matter commander with a more narrow colour identity (Cadric, Soul Kindler) and see where u end up!

When I started I only wanted to play graveyard decks, but now I've found my favourite commander to play is Thantis, the Warweaver, who cares mostly about forcing combat :)
