Hi there , recently I've been having some issues with my game completely freezing for between 5 sec to about 2-3mins at a time, then it all jumps forward and all sounds etc that happened during the freeze happen at once.
The part that worries me is that it seems to happen only when I'm doing arena ( mostly in 3v3 ).
I thought it might be my computer not handling the game at full settings ( with some settings turned down ) but that's proven not to be the case.
I then noticed that I'm getting (World) MS usually at about 2k when these problems start happening. It starts with spell lag and minor freezes when running around Durotar , and when I try to do Arena it gets so bad that sometimes I can't even get out of the doors to start the fight. Doing a /reload works about 2 out of 10 attempts but when it does it only helps for about 30 seconds then I get the same problem.
The strangest thing is that I've not seen this happen in any game besides World of Warcraft. I don't play any other MMO games but in online FPS I run completely fine after I've been having issues with WoW. My arena buddy suggested that it might be a problem with my internet provider or some sort of Port or Firewall block. I've tried all the basic methods that come to mind ( in-game options , Firewall off etc ) with no success.

Results from a tracert just after getting about 5k MS in WoW and major freezes :
