Hi, my character name is Icecreamsky on 100x realm 5.4.8 MOP server, alliance side. 
Class: Enhancement Shaman. Race: Draenei. 
         I have a huge issue like the mentioned in the title. To be specific, for example, if a rogue saps me or a warlock fears me or I have 5 stacks of maelstrom weapon like this pic:[ATTACH=CONFIG]84736[/ATTACH]   
 I should be able to see that particular symbol/warning  in the middle of my screen but I do not see any of those. That applies to every single CC in the game. 
         I tried to reload UI, disable all my addons, tried both x64 bit x32 bit client. All of them don't work. Please help me. Thank you for your patience
