....nice topic kaey. though i disagree with few point in article. yes the main Tank is the top concern, nevertheless , the dps need to be top off too otherwise they will die if the encounter boss dose long-Range AOE damage. if they die. you all die.
yes if you lucky and know your enemy hit+crit, then you can participate his/her actions. mostly we will learn by trail and error.
Healing is not for everyone,healer is for someone showing the capacity for endurance. its very stressful. people will eventually blame you for everything, their death , especially those noobs who will pull boss aggro from Main Tank to show off they are hardcore DPS. what good is dead hardcore DPS.
i know from here. i will be grouping with my friends only. if they start a guild. most i will group with them just to avoid hassles .
i have learn from 4 yrs in WOW as healer and sin (Rogue).
