You know you play too much when you kill a mosquito at work and yell out "I AM THE HUNTER" Have you ever had a similar experiance?

I feel like I've been out of groove lately. Ever since I started using sheriff in deathmatch, I've been worse with every other gun. I've also been trying to master other agents aside from Reyna and I've been losing because of that (solo q)....

I currently have a 144hz 1080p monitor thats 24.5" and im going to upgrade to 240hz, is 27" a bad idea? Will the lower resolution at a bigger screen be a disadvantage?
