Consoles: How do you do the nasty strafe?

@Cheese9ManI was going to give the answer in a long boring story but I decided to give you the short answer
Get a controller with paddles, am using Astro A40 but there is alot of other options .
That's for the crouch spamming , for strafing you just need to train everyday but with back paddles you will get the crouch and strafing combination which can be very very effective 🙂
