I'd like to start off by saying that I for one love the new difficutly of the Heroics. Having to CC (until better geared) has brought back more of a challenge to organization and alertness to the game that i thought was missing for all of wrath.
That being said, i'm findint it more and more of an annoyance when i go into a group and the CC symbols used are different all the time. I'm from the BC mindset still where sheep is always moon, square is trap, diamon is sap, etc.... I think the only constant is that skull is first, i've even seen X used as a cc marker. I can already imagine that many of you are thinking 'it's just a heroic, it's not that hard to keep track of one symbol' or 'if you don't like it, you mark it' and i would agree for the most part. However, when you are in a group where you are out numbered by a guild from another server, they usually don't take to kindly to suggestions from the pug dps. Also, i have seen many many instances fail because after the 2nd or 3rd pull people are ccing the wrong thing and the loose add causes a wipe. The obvious/easiest solution would be to have a different symbol per form of CC (not just by class because there are several classes with multiple CC). Unfortunately, there are not that many symbols available, and i can't see blizzard putting in that many more.
What i'm hoping for as far as feedback is of course suggestions to macro/mark maybe before each of the first few pulls, or maybe the name of an addon that (if one exists) scans the group make up/talents (is the hunter spec'd for sleep) and assigns the targets based on available CC. The last option seems too easy and starts leaning more towards defeating the difficutly/challenge of having the CC and so you see my problem.
