I can't believe all this vitriol about coincounter
he does four things all with very long windups and telegraphed stances.
And if your using half decent gear they aren't one-shot kills. That only happens to the people using level 40- white gear from quests
Every MMO's top content doesn't use many telegraphs and will even put in telegraphs that are lies just to make sure the players are paying attention. Even the 24-man raids have un-telegraphed stuff and ambiguous markers you need to learn from trial and error and those are heavily played all the time and usually the most well liked content in the entire game
If you can't learn four extremely simple things just from observation not sure "bad design" is the issue
