You sometimes get these overbright spots/areas that never fully converge no matter how long you render it out. Which is something ERPT was supposed to counteract
In scenes with complex refracted caustics highlights, it's pretty much luck if you get any of them to show. You will get some, but it will be random from render to render, and you will never get all of them.
That's the thing, too much luck involved to be called a robust rendering solution.
MLT is after all, a random walk rendering style. I wish there was something better now that was not left to chance.
MLT is damn old in computer years!
Wait isn't MLT usually used with bidir? Because it seems to me that caustics converge very well and consistantly with that. AFAIK, MLT is not just random, it is a very smart algorithm.

It seems you are just bashing MLT for no reason
