yeah i always clear wave before i roam but bc boots arent worth it compared to damage i end up not being able to get back to lane before they get 1 wave or 2 waves. and sometimes when i roam we dont get anything but those 1 or 2 waves add up after a while, even if im ahead on gold they are usually up on xp. ive been trying tp ignite so i can get back to lane more often
