Pointless, as each raid fight is different and the experience does not transfer clearing t9 when it was current in no way helped me in A1s.

MMOs tend to not teach players how to play their games properly and they just relies on the communities to do that for them that really needs to change. Just point people to these fourms for rotations and make them aware of the 2-3 video guides for each fight and give them the chance to go in and do the fight.
