Destiny 2 Has No Endgame?

I kinda feel like there's not much for the end game cause I've hit 305 and now it's just grind for gear on my other characters. Running the raid was a pain in the ass (at first) and it's not a good balance of raid mechanics and add control. I understand that there's a need to punish the people that aren't good at mechanics, but to punish the entire team is a bit much. And it only takes one person who doesn't want to help to ruin it for everyone. Not to mention that anyone without a mic is screwed. The nightfall is also not quite helpful because it either is too difficult for people to grasp (I've helped my friends out on more than one occasion) or it's outright too brutal for the average player. My friends have helped me with a couple runs but that took them a couple tries for several of the strikes just to understand how to efficiently manage adds on top of the challenge and the time modifier. Plus the worst part about all of it is the fact that you get kicked to orbit if you don't get it in time. While it adds a certain amount of pressure and demands a higher level of skill, it's near impossible for anyone under 280 to do it reliably, and it's not fun to be at the same thing for 4 hours and repeating the cycle every ~20 mins because of one failure at the very end. I will say that Bungie has created a wonderful game to explore and play in, but it doesn't have much to do when you've "completed" it. I'm still playing it to help my friends out or to boost my alternates so I can be a well rounded replacement for whatever we happen to be missing when it comes to planning a raid group (if I end up playing it, which isn't often), I just feel like there's not enough variety after having 3 years of D1. One day it might get there, and I understand we're at the beginning of it all, but it's a slow burn and I'm ready to play AC Origins now.

I feel they may need to institute a complete revamp to the Trials of the Nine, given that in its current form, it is merely just a more focused form of the current version of Iron Banner. Trials of Osiris worked so well in Destiny 1 due to how truly competitive it was and how hard it was to go Flawless. By comparison, TotN is, as I just said, just Iron Banner with a win/lose card. I feel they could overhaul it with some kind of tier system, with a flurry new game modes that put your skills as a competitive player to the test, with a win/lose card that not only tracks your wins and losses, but serves as a checkpoint system that dictates which mode you are going to be playing next as you work your way up the chain.

Also they should just bring back Trials of Osiris if they don't. The current set-up just doesn't seem to work for the balanced PVP they said they were striving for.

tl;dr : Filthy casuals are ruining game industry.
