    <Because you should be happy running around turret opposite your enemy>

    Description:

    Basically we've all known about juking under turret. Especially at top lane when (s)he wants to dive you.
    Because sometimes juking under turret is what will help you win the fight and ultimately kill him.
    We've probably all succeeded at this sometimes and sometimes we misclick and walk right in to the enemy.
    But what if, there was a way to do it without fail. Provided you turn it on when needed. :P

    Tips:
    -Turn it on when you feel like they will dive you at turret and you want to juke them.
    -Be smart, if they have a gap closer like xin zhao this probably won't work. But then it might to some degree help. (He dashes you flash to other side and proceed to juke)

    HOTKEYS (for different users)
    T-Stay on or off
    V-Hold down to turn on, let go to turn off

    I recommend V. :P

    Notes:

    -Currently supports single targets. Might update later on for 2 targets to determine best position but more than that and I'm pretty sure you should just leave that turret.
    -No dead turret check because you can still juke around the remains of a turret although it'd only buy time..
