I was looking for rotations on youtube to try to learn BLM and came across both of these. http://ffxivrotations.com/1hke
http://ffxivrotations.com/1bpy
One is considerably longer. Can someone please tell me

1) Are these still current rotations to learn?
2) What would be the different situations to have for these very different rotations?

Any help would be appreciated. Thanks a lot
