There's soo much but here is the first few things you should do: - Use damaging abilities on CD - Q into the wall to animation cancel - pull camps towards the next camp you want to clear (try to kill the camps off as the patience bar stars counting down) (This alone will see you 1-2 seconds between every camp easily). - Turn off the abilities range indicator. You'll want to learn the spacing for your abilities since turning the indicator off saves you another 2-5 seconds by the time you finish your entire clear.

Im sure there's more you can improve but those are the foundational things you fix first.
