ill try to reply to some from my point of view

also use the search function, ellay already replied to many of these questions before


the reason for having the healer in the front (especially with pally healers) is to 'draw agro' this keeps the opposing team in FRONT of ellay's shamans, no need to turn, just blast
the pala healer can always bubble when needed, and is in better range to the opposite healers in order to use hammer of justice RIGHT before ellay blasts the warrior down, without the warrior getting shielded, bubbled, healed

follow: i have /follow macro binded to ~ key, in reach of my pinky, and gotten used to mashing it whenever i think it is necessery, works nicely
i dont like having /follow in other macro's, as often i like my alts to stay put while i move around

for any other questions, use the search, read around, enjoy your stay
