Okay, so since all of you are going crazy what's going on in Elanns video.
1. If you reforge full haste as a rogue and you use NORMAL Matrix or Hungerer on top, You will get more than 5 ambushes off in a Shadow Dance. It's not supposed to be like that, even on warmane with full haste you couldn't have this energy regen as you do on ATLANTISS. YES it's a server bugg, that they didn't fix haste for Rogues and Ferals properly.
2. Once your energy is above 13.00 It buggs out crazy as you can see in Elanns video. This is also a server bugg. Nobody knows how to do it, I believe it all happens when you eat too much CC in arena and or it's a talent bugg with Recuperate. I don't know. Also, If a warlock cc's you too much in arenas, you get this server buggs that makes you immune to all stuns, roots etc. Dying or Relogging fixes it.
3. All the screenshots that's flying around. It's to make it look "Cool" but yeah I really don't know how to do it, it's a server bugg that happened like 4 times to me in whole 3 years of playing.
I noticed something was wrong, when Lingu and Qbab, and a horde rogue called Zatana or smth was doing crazy damage.
There you got it, Stop crying and all the HATERS come at me if you want. Beside this you can see on my TWITCH and VIDEO, everything so. IN THE END WE'RE PLAYING ON RETAIL CALLED ATLANTISS, WHERE THERES NO BUGGS AND EVERYTHING IS PERFECT but yeah L2P and have a good day.
Ps. I guess you've got your excuse now when you lose to me in arena^^
