Well, not really, but when it comes down to it, it annoys me quite greatly.
So the problem I am facing is what feels like a fairly common case of "People aren't doing the boss mechanics properly, wipe, and then are confused and outraged by said wipe", this is when I am doing something like Cradle of Shadows as a tank, or any otger kind of dungeon that has a certain mechanic that requires a change of focus or for you to interrupt something.
I have stopped wanting to play a tank just because of Cradle of Shadows' second-to-last boss. With DPS whailing on the spectres instead of interrupting them, leaving me to essentially die (Not to mention one occurence had me kicked by two trolling party members who were acting like Dumb and Dumber)
Am I the only one who thinks that there need to be more signals for the especially blind people to react to? Perhaps a loud blaring noise saying "Interrupt!" Or "Focus on Target!", or am I crazy thinking this?
