Leonardo is bugged
Whenever a champion that uses an ignore stone skin ability against a Leonardo(without other turtles present), you would expect Leo's passive to be null against the ability because it reads that Leo preempts damage to just place a stoneskin if he would take an amount of damage that is going to reduce his HP level below 50 percent. This is not the case, at least, with Georgid. I have consistently been unfairly countered by a buggy Leo passive when using Georgid's A3 ability which is, again, supposed to ignore stone skin. This is very frustrating and would be an easy patch.
