If you play 3x3, a single platinum plate does not make much difference. A mythical resistance only physical as I have, represents more a problem than a solution, because you don´t know where to place it or when.
Here we are talking about people who are carrying 4 to 10 platinum plates (counting their 3 mechs) and combined mythical resistance in each of them.
You cannot compete with that. And in view of how difficult they are to obtain, I find it hard to believe that they have got in 6 months in a clean manner. I’m sorry if I’m unfair, but I cannot really believe.
