Honestly just practice that's where you'll get better and learn it all. Everyone plays differently, the people on this forum are definitely more hardcore. Like I said before I've never had any problem doing any floor of alex, and I never pay attention what combos or whatever some DPS is doing. I get at least 1 commendation probably 95% of the time and I've never had anyone yell or say I'm healing wrong. Point is, this forum is great for getting help and information, but it's not the end all resource. Play however you want and practice and learn what works best for you.
