Yeah.. a guy like Jeff Kaplan who interjects his own ideas and hockey anecdotes for 0hl rationale isn't a good game designer in the slightest. Why would you take a formula that has been proven effective not only in other games FPS and MOBA alike (League, TF2), but in Overwatch itself with the competitive community, and throw it out the window?
A developer shoehorning a meta instead of letting it develop organically in the competitive community is pretty adverse to the game's growth. They have a history of this with their other games as well.
In a case study of developers like Riot Games, they can make such influential changes because there is less of a disconnect between them and the competitive scene. With Blizzard it's as if it's an isolated case of a couple of dudes theory crafting what they think works vs what's been proven to be successful competitively.
If Blizzard is trying to encourage more hero diversity and switching, 0hl certainly isn't the answer. Yeah let's just pit 5-6 of the same heroes agaist each other, more diversity. 0hl is not only less fun, but more hectic and viewer unfriendly. Also a side effect of 1hl, competitively at least, is that people can "main" heroes instead of having to be jack of all trades, creating more of an identity for themselves as "that Genji" or "that Lucio".
I think the development team should have competitive players themselves, so they aren't just people throwing ideas into a black box. That, or community managers who are in touch with the competitive tides of meta.
Taking a look at a popular non FPS/MOBA, the Dark Souls franchise for example. At least the head of the company is keen enough to improve on what works and isolate what doesn't. That's why the games successfully iterate on predecessor titles and Miyazaki is a genius. Kaplan has only ever been a game design for Warcraft-esque games. He should be keen on listening to reliable feedback.
If you don't think 0hl is abysmmal after watching it, you are borderline dysfunctional. Pretty sure this sentiment is echoed universally by everyone except Blizzard and Jeff Kappan.
