Making sure I'm doing this right
As Orianna Mid.
(ignore my builds, I just build the way I like or that helps me instagib things)
Early Lane Phase: Deploy "The Ball" near your opponent and use it to scare them away from cs. Save some mana for heavier poking to keep them under your level/less gold supplied. If gank comes, barrier and hug turret....
Mid Phase: (assuming a tower is down somewhere or no one is laning) Roam to whichever lane is pushed farthest and gank it. Try not to team fight unless you have lots of mana and/or ult.
Late: 1v5. Just spam the Q and E in team fights to litterally melt the enemy team with as many W/R as possible (usually just 1). Its like playing with fire.
Rotation: Q past target, W during travel, E immediately after it stops, Q again. Ult. Repeat.
