Sniper Glint Attachment

Why would we need to nerf the glint and give it a massive cone of vision for all players to see (including tanks) which are completely out of my view (within the scope). Just so you guys can add an attachment to the game (AG Coating) that basically becomes a necessity?? You might as well just remove some points from the sniper and force the AG Coating to be a permanent feature to the sniper. This extra attachment makes it not possible to have a decent build on the sniper.

I couldn’t find a way to add a suppressor without having to completely mess up my sniper to have no AG Coating. Which at that point becomes useless because they can see my glint like it is the sun.
