well, the thing with EJ is - they are theorycrafters

while they can mathematicly provide numbers or spreadsheets how some stat is better or how you should do your spell rotation - those are best used/taken with a grain of salt

be it raids, heroics or even dungeons - situation changes from time to time. most raids have enrage timers, movement coordination, target swapping or even damage/healing control. plus we have more 'nature' elements have to factor in - skill level of your buddies(a huge factor if u pug alot), average gear level, and the dreaded latency.

so realisticly speaking - even if you are geared exactly to their spreadsheet, your raid/group experience would still vary as it might not be optimal for your raid instead

my advice is - while u can follow their 'golden rule' on how you get geared, its best you try out yourself which works best for you.

of course, there's still the basic standard requirement you must meet - no point having 2000mp5 but your heals sucked
