At least the increased recoil for Electro & Toxic Brainz can be kept away for a while longer, but I strongly insist that they don't implement that change for both of them. In fact, I want the recoil for the other variants of the same class to be reduced significantly, because after all, I hate the idea of wrestling with the aiming during use of the zoomed weapons.
As for implementing the changes, with the way those issues are presenting to the dev team, it's not funny. If they are going to properly implement the changes without any unforseen bugs, a game update would be ideal. The last time the game received an update was way back when the Frontline Fighters DLC was released. If they do that, and frequently update the game once every few months for performance optimization, GW2 will be back in full strength.
