Everything still suggests Archer fought Berserker in melee, and if you consider it logically, Archer did not really have a choice in the matter.
It's not really a recton, since the VN also mentions the ranks of attacks. It's adding detail, if anything, but Apocrypha wasn't written by Nasu anyways.
Technically he can't trace it properly, since divine constructs are outside his ability to reproduce (Avalon aside). So if it was Excalibur he traced, it was a more degraded version than most of his projections tend to be.
If you wanna talk about wanking, then please also start complaining how Berserker can fight using his skills despite the fact he's insane. As my original point, just because Ufotable changed things, doesn't mean the changes are bad, especially if they're across the board in a way that keeps things interesting.
(Following my train of thought that Ufo probably decided to close a blind eye to how Saber was nerfed in the VN because of Shirou, her having Strength A is also not out of the question, as she has that rank under Rin. Though, again, I dislike having to bring up Ranks because they're a retardation that only serves to occasionally burden arguments about the narration with fallacious and contradicting information on the account of Nasu adding them because he liked the idea of faux RPG mechanics.)
