Mind control disconnect

This has been happening to me a lot in PVP, especially in RBGS…cast MC and it dc me instantly out of the game at the end of the cast, then i cannot rejoin for over 2-5 minutes, stuck on full loading screen, can hear everything happening in the background, have to alt-f4 like 3 times to get it to load back right and low and behold, many a game lost as im no longer healing for over 2-5 minutes sometimes. Please fix. I swear i remember this happening up to 4 years ago and all through up til now.
