if you play with china player .they will show you how to beat guy who move his mcv to mid .when you think the mid dont have weakness,on the other word ,it is say you heck is not very good . IN china ,if you are top player , you know the weakness of the mid heck.
Moving mid may have a weakness, but it is still the best thing to do, or people wouldnt do it!.
In yuris revenge people played with no mcv repacks to stop this. Sure moving mid you are behind, but all you have to dois survive for 7 minutes and you cant lose, you have so much money!
