From what I read it's an overall nerf actually.
The changelog is kinda confusing tbf.
I've been getting headshot since this patch so much it's ridiculous, before this patch getting headshot was a lot harder, virtually every time I die to an archer now it is 85% of the time, a headshot.
And most of the time that's with me zigzagging. This is by no means a nerf what so ever lol.
In fact, overall archers received a massive buff due to the killing off of most xbowers as they were massively nerfed, so now the only viable option left is Arbalest (If I'm thinking correctly, there might be one other xbow that isn't ruined) But yeah, for the most part, xbows were the largest counter to archers as most of the time archers are stationary leaving them open to being shot by xbowers, however, now it's a lot harder due to the nerfs they received. Not every buff has to be based on whether archers themselves were given it, it can also be based on whether another class was shut down, and in this case, it's true.
(Okay the below point isn't directed towards you Molly I'm just venting at this stage
)
To finish, archery hasn't been directly buffed, however it's now 100% easier than it was before, meaning archers can dominate everything and we can't do fuck all about it because fuck everything but archers. And don't give me "WUL JUSS GIT A SHELD111!!" because that excuse is bullshit.
