Could be, could be, altho i said that guide is outdated so you should focus on the other one i linked before everything in the guide. :D
P.S. Here are Logs from my last raid:

On most of the bosses i was slacking due to real life getting in the way.
On DBS and Rotface, i was trying some new openers, while on BQL, Sindra and LK i was doing just fine, without any checks or interuptions.
(PP was awfull, worst player warmane, i got hit by goo and stepped in choking gas so many times i wanted to delete the game)
