I had never seen normal ports fail like gates collapse, or leave people behind. The evac even had a chance to leave a wizard behind that had cast it. I would almost agree with it, if it was set at below 1% chance, since out of 6 years playing on live, not once did anyone get left behind with a normal port.
It always had the risk vs reward for using the spell over the normal ports. Either you use it, and get out quicker with a chance of leaving someone behind. Or casting a long spell, and you all may die waiting.
No idea if this should be attached to the Skyfire/EJ evacs. I know they are considered evacs by the casting time. So most likely.
Maybe I am off on the percentage of each person. It did happen rarely, but it did happen. I just consider 15-20 out of 100 rare!
