If this is what you're taking from the conversation you haven't played enough archer lives or aren't paying attention. I respect Ying. However, his view is focused entirely on DPS in a controlled group environment. For 95% of people in the game environments they will play in, a Dino Bow will be a better choice.
“This” is an additional comment for context and emphasis. The rest of my post that you didn’t quote was the core of my message.
You’re also forgetting to talk about something very important if you want to encourage people to have flexibility in their weapon. If you want more flexibility, the answer isn’t “get a Dino bow.” The answer is get multiple bows. If you are soloing or you’re in a PUG, you’re going to need to take care of every helpful/necessary weapon effect on your own because you can’t count on the rest of the party to supply it. They might have what’s helpful/necessary but they might not. My nuker has 5 Dino sticks for exactly that reason - when I need to, I can contribute anything/everything that’s helpful from those effects. But none of those 5 Dino sticks are “the best nuker weapon”.
I think that some of the issue also comes down to different people having different understanding of what “endgame” means. If you think “endgame” is just anything level 30+ and you are just running R8 Grim and Barrett in a decent PUG, then just bring whatever. LGS Salt, anything with Freezing Ice type procs, Pinion, Sapphire Sting, an unattuned Dino bow, whatever. It will be fine. But I don’t think that’s “endgame”. I think a decent definition of “endgame” is the legendary content that you can’t consistently beat - the stuff where you have to work to get a completion and you know you might not pull it off because you’re pushing your limits. In that kind of content, you need a group where everyone is contributing the kind of things that you get in a controlled group environment. Because you aren’t going to complete endgame content without a solid group where all the big items are covered by the party as a whole.
