your post would be a lot more effective if it wasn't so long winded, but I agree with what you are saying. Think about it if you see a piece or rare/ex gear with materia in it, that means that person has crafted it themselves because its untradable. If you see stacked rare/ex it means they have gone to multiple runs to get that item so they can keep attempting to put materia in it.

Basically if you see someone with a 5 socketed rare/ex items its like they win the game. like how bill gates just got an honorary degree from some college. You just GET the win.
