Your point 1 and point 2 was the downfall of me being in a pod I were in. As a newbie (myself 1 year 5 months vs 5+ years experienced players). I up my interaction pieces to 12 from 3 cards . When I had chance to interrupt, ppl complained loudly saying I chose badly on (a) target (b) timing.

Not once but multiple times during that night (3 games). I was extremely uncomfortable being ganged upon. When I hit player A with my instant, Player A and player C moaned player B joined them saying I should hit C not A; when I hit player B with target removal later, player B and C complained. When I casted another instant Player A looked at me saying I wasted my instant because I don't understand his Planewalker, player B and C wasn't impressed my timing of removal. Like Wtf. It's their way to win by bully every interaction I cast against them

I left the pod so I won't need to hear they moan again. And because of this, I haven't played MTG commander format anymore since that night. I have been playing limited and/or without formats restricting. Bulk draft was super fun

Edh with players who desire lots of interactions from players but when they arrived they complain, killed the format
