As someone who loves using rifles, this patch is great! it brings all the rifles up to being really solid weapons, and all of them feel viable to use now (at least in PvE, I don't do PvP so can't comment there). I'm a little sad that the Harris wasn't buffed as it's my favorite weapon, but considering I always have used it because it was already strong, it's fair to leave it as is.
Can't wait for the PvP balance patch, as hopefully it brings even more weapons up to snuff for PvE as well. There are a lot of weapons that feel kind of useless right now, and others that just completely overshadow everything else with how powerful they are. But this patch is a great first step!
