1) In the Range, practice moving the crosshair minimally. Understand the flick distance, understand @ what point you overshoot the target, then focus on either (A) hitting the target square or (B) coming up slightly short of the target.
This is ideal, so that you can simply follow the direction of the aiming with your strafe to correct your shots. Overshooting means that you need to strafe in the opposite direction to microadjust your shot.
2) In Comp settings, try and pick apart the other team's tendencies. Look for emerging patterns and positioning. For example, in the Lotus match yesterday-I noticed that whenever KJ had setup her turret in B main, that the rest of the team would heavy push A.
Mo made a terrific read when we switched sides as well. His tip was that in the maps where there are three sites, that we should avoid taking on a particular site (such as C) and only go after the two other ones.
When it is a critical round that we need to win, we heavy push onto the omitted site.
This is great because in the round that follows, the opposing team will be very confused as to whether a strong A push will come, or if we will repeat the C push.
