You've seen all ~1000 Bungie employees play their own game?
You trust a single person's experience over statistical data?
There could be someone just as skilled at the game at Bungie, but it still wouldn't necessarily change the current state of the game, even if they agreed with him. Like, for example, I doubt Zoba is aware of the statistics on how cooldowns play with network performance, as almost none of this stuff is published.
Armchair design is fine, this is NeoGAF; it's the arrogance of "I know what's a better design without data" that irks me.
No, I have not seen all 1000 employees. But I can evaluate their effect on the game.
I'm not just going with Zoba. I'm going with my experience, the many people who have been discussing this in the Destiny OTs for literally years, the hundreds of posts analyzing the Crucible in r/crucibleplaybook, and the testimony of many top-level streamers.
Against Bungie's 1000 employees (only a few of which actually matter, btw), I'm willing to believe that the literally millions of people who play every day have a more valid perspective on how the game feels.
Statistical data has its place. But so does the community. I don't think that Bungie has done a good enough job in engaging the community in how Destiny should be evolving.
They make changes to the meta that are mind-boggling, they misrepresent the changes, and are obstinate about reverting changes that are universally despised.
So sure, it's all subjective. But that's good. And Bungie should listen.
