On the Mane 6, Spike, the Cutie Mark Crusaders, and certain characters.

So far, most of the antagonists who aren’t in the season opener+endings and monsters haven’t really done that much more damage than the Mane 6.
 
As I brought up in another topic, Spike rampaged through Ponyville after getting big enough, Applejack’s incompetence lead to ponies being poisoned (and as I said in the other topic, there have been lawsuits for as much in our world), Fluttershy brought that parasprite to Ponyville and Twilight kept it around, half of the mane 6 heckled Trixie’s show and how Spike acted towards Twilight after she made it clear she didn’t want to confront Trixie, Twilight used her “Want it, need it” spell which led to a brawl with several ponies, Fluttershy learning from Iron Will and then terrorizing several townsfolk, the incidents involving the Cutie Mark Crusaders etc.
 
Compare this to Trixie (who didn’t really do that much damage until after she got the amulet), Diamond Tiara, etc., and you can ask if those characters are really that much worse than the Mane 6, Spike, and the Cutie Mark Crusaders.

In the instance of the Cutie Mark Crusaders and Spike, I’d say it’s their own damn fault for not keeping a better eye on their dumb children and leaving a being who’s biology you know nothing about in the bonies, respectively.
 
But you do have a point. As an addendum to this, let’s bring up the Six’s behavior in Canterlot. Just because someone has different tastes then you, it’s okay to trash their parties and ruin their nights without consequence, all because your absolute ruler didn’t want to handle the paperwork that would come with changing things herself.

Add Rarity conking out those three Wonderbolts despite being repeatedly warned about her magic wings.

Yes but you forget that the mane6 have also saved not just Ponyville, but Equestria multiple times.

Yeah, I’m pretty sure that when you have saved the world multiple times, you end up getting alot of leeway with things.

@GreenHair Carrot Top
 
I would like that to be an actual in-show thing, having some characters grumbling that the saviours of Equestria destroyed another event, and how they can’t really do anything.
 
However, that doesn’t really excuse the CMCs.

Sisters.

I love it
