If you wanted to be Raid ready at 1pm EST Friday, that is not true.
I can appreciate those people who want to burn through the content asap, "world first" and people who like to keep at the head of the wave. For those people I understand that limiting progress will be frustrating.
And I also understand that releasing the raid a a week after release of the DLC seems contradictory to the limited progress as it makes it seems as if the delay was intended to allow people to get ready, but to get ready in a week you need to either game the system or grind like hell.
So the design of the game is contradictory which will inevitably lead to frustration, I get that.
I agree that Bungie should have catered to both types of players. If they left in a way to grind out hard to reach raid level in a week then they obviously intended for it to be possible (Omnigal farm aside), so they absolutely could have included a variety of ways that were as efficient as the others to reduce the feeling of grind.
However, there is no need to rush for the raid. And if you don't rush, you can play a large variety of content and achieve steady enough progression that it always feels like what you're doing is worthwhile.
So yeh, if you rush for the raid you are forcing the grind on yourself. At this point when we understand the system especially.
I'm glad I didn't rush for the raid day one. I have friends who are taking it slower and looking forward to a blind raid sometime over the next few weeks. It really isn't difficult to avoid spoilers (this forum and the discord are the only places I frequent that talk about it, and even then it's easy to spot posts and just skip them) and I'm feeling no burnout.
I do get your frustration though, don't get me wrong.
