Network connection constantly disrupted while in-game

Hello,

I was doing the Reforge the Blade (Quel'Delar) quest, when I was on the RP event with Blood Queen lana'thel in Icecrown at Quel'Delar's Rest the game froze and DC'd me. Ever since I can be online anywhere between 10 seconds and a minute before the game freezes, my connection is reseted and I DC.
Discord/Chrome dies for these seconds as well. I have no issues using other online applications, it's only with Warmane.
I've spammed ping google.com in CMD as i'm playing, I stay on a stable 20 ms no packet loss and then suddenly Timed Out over and over. No such issues outside of WoW.

I've cleared Cache and WTF, I've rebooted my router, and now i'm re-downloading the entire client. Please help.

Update : Having redownloaded the client seems to have solved the issue.
