back to watching the angles, just figuring out good spots to hang out is largely a common sense thing, but following in the footsteps of someone better will usually be rewarding. If you look at https://streamable.com/wup42, when they move to engage their first enemy, they clearly show that they *do not* understand the concept of good angles, or don't know the map well enough to know that they were walking into a shitty spot. Angles are all about maximizing your defense and visibility on enemies, while minimizing your exposure to fire. Getting in cover and shooting over an open area the enemy is forced to walk through is a good angle, standing in the open surrounded by windows and doorways is an awful angle. Standing in low ground facing an enemy who is a full body's height above you and completely in cover is a horrible angle. All this does is maximize your survivability, and in a good spot, give you opportunities to net some easier then usual kills. 
Another important note is proper form for actually engaging. Lots of times, people like to just stand around in their safe spot and wait for the defenders to come out of their hidey-holes so they can shoot without having to walk around. This absolutely does not work ever, as not only are you not planting the bomb or clearing the site, the defenders will just adapt to your position with better spots or throw lots of exploding rocks at you. When someone tells you to move in, move in alongside them and poke out of your cover at the same time without blocking your friend's line of fire. This means you get two guns shooting at bad guys at once, and the bad guys get two people they have to shoot before they're safe again. Poking in one by one is horrible form and just pads the kill counts of someone who can actually aim with infinite 1v1s, whereas a 2v1 can quickly flip tables. Figure out how to do this and practice good form for a rush and rounds will consistently be easier to win.
