Subaru WRX engine reliability

So I am looking for my first car and a few used WRX's have caught my eye.
However, my friend who is a Subaru fanboy has informed me that the
engines are "Prone to ring land failure. Ej motors are known to blow up.
Bunch of engine problems since Subaru hasn't changed the engine in over
15 years" He has also said that I would be almost guaranteed to blow up the
engine and would have costly consequences. Upon research I have found a
few videos about ring land failure existing but I haven't found a video
describing the engine to have the problems he described. So I was
wondering if there are any ways to prevent these problems to make this car
reliable.
