I think I had this discussion before. I'm not a fan of this approach. Hopefully this year's DDT event will result in more support so they think it's worth it to try.
They've made efforts within their means but like the English commentary shows but since they're not live, nobody watched. It really just leaves promo packages and live English commentary. The former they don't really do much of and the latter would be extraordinarily difficult. Finding a commentary-ready voice to digest and re-express with a modicum of comedic timing or awareness sounds impossible.
Definitely room for improvement but it'll never be what people hope it would be.
