What GW2 raids would be like with WoW's addon, "DBM"

DBM stands for Deadly Boss Mods, a commonplace addon in World of Warcraft widely considered as "required" to play the game. This addon is capable of calling out/displaying a timer for every mechanic in the game. The depiction in the video is fairly accurate in my opinion except the timers can show you mechanics 30 seconds in advance. I just went with ~8 seconds because 30 seconds would be too much work. Also, for the shackles mechanic, DBM would force both shackled characters to say something in chat so that a chat bubble is above their head to show you who to run away from. So, yes, it's even more OP than it seems in this video.

The addon honestly kills my enjoyment of the game because it pretty much removes the need to learn the boss.
