It's an improved version of CleverName's build so no, it's not a 2020 build and it most definitely is more META than like half the terrible builds posted here.
More nonsense. The META changes if the conditions change, new items, nerfs/buffs etc. I certainly know more than you given the stupid claims you've made, if you're going to be the messenger at least get familiar with the material you're presenting otherwise you'll end up looking like a buffoon e.g. insulting a mod setup presented by me despite the same mod setup being used by some of the builds you posted.
From what I've seen several top players came on here to say that the builds presented aren't optimized yet, you're the only one embarrassing yourself and not knowing when to stop talking.
I've already explained how that is not true, most of the builds presented by CleverName are still being used with very slight alterations. I think the explanation is quite clear, most people don't have CleverName's infinite inventory so they had to make due with altered builds, what's being used the most =/= META
Well that explains it.
