This is the fourth time that I have come across an IO player doing this. They leave Luna in the base, then when they "die" they sit inside the base till Sacrifice is back online. Never able to be killed. Sacrifice should only work when Luna is outside the spawn, and the cool down should be much longer. It is already as strong as an ultimate ( it is basically terminus Ult minus the damage) but you put that on a 45sec timer?! If your not going to remove this broken talent, that at least balance it so its not fully broken.
