Bloom adjustment may be needed yes. But they need to be careful not to make Hand cannons the mini snipers they were in early D1. That's why Bloom was upped there. Flinch is fine. Not sure how accurate your "1 year on Bungie.net" is but if you weren't here to understand the Sniper meta in D1 then you wont understand why flinch is the way it is. Sniping in Destiny doesn't have bullet travel or drop. It needs to be able to be countered effectively or it becomes too easy to just run and use. This includes enough flinch so that even 1 shot affects your aim. You should not be able to maintain aim through bullet fire (getting hit). it has to be there and right now it's a good balance. Good skilled snipers can pull though it. Mid to lower tier skill are going to have trouble until they get better. All as it should be.
HAHAHAHAHA Console Players ask for this since day 1 of D1, guess who gives a shit about you?
