With Blms still having a line of site limitation(not sure why they have yet to fix this). It is a real pain in the ass. If you and a MCH/WHM/Garuda happen to be on the same mob. Your DPS rotation can be utterly destroyed by this one move. Although as a temporary solution. If I'm on BLM, and I have any of those jobs in my group. I try to stand next to them, so that its extremely unlikely I will be interrupted. I wish they would just fix this LoS issue already.
