other ppl have mentioned mods and JKLS and the weird r9 thing, so I will just say this:
Are you in a guild?
A huge part of the importance of a guild is that it gives other players the incentive to help you, bc when they help you then your roster improves which helps them in TB, TW, and Raids.
If you are not in a guild with a Discord channel where you can drop into the chat, "Hey, I can't beat this event. Can anyone help?" and get 6 volunteers to help you over the next 6 hours, then you're not in a good guild. You need and deserve better.
And if you are in a guild that helps each other, but you're here, then you need to realize that the bad player holding everyone back is you, bc you're not participating in the guild's culture of mutual support. I mean, if you're not asking other people for help, you probably aren't helping other people either (or if you are, you're acting better than them for having solved it and you offer advice only to prove your superiority).
So go to your guild, learn to accept and provide kind, generous help, and make your guild the force in the galaxy that it should be.
Or, if your guild is toxic and the reason you're not asking for help is bc they're bad not bc you are, then leave your guild for someplace better and your entire experience of the game will be much improved.
Guilds are good. Participate in your guild. Build something great.
