There is still a use for them, however this allows for a DD BLU to be more versatile then having to go back to swap out atma and grab gear out of the mog sack, that towards the end of a fight, you can use this ability convert the damage and zerg away with little repercussion to TP feeding. As I stated before this ability would have a pretty extended recast counter so it would not be abused (I'm thinking 8-10 minutes might make it more fair, I was hoping more for what I listed before for more frequent use, but eh). Then again I suppose I'm biased because I still dislike strongly Magical BLU's, and I'm clearly a Physical BLU, yet I still would say that if you are going to fight some crazy NMs with nasty AoE's in which you don't want to be close, you are still going to use Magical BlU's. Your not going to use this JA to compensate, because it won't be enough. Also a Duration of 1-2 mins isn't going to kill a mob or throw Magical BLU's out. Its just going to be a game changer towards the end of a fight. So there still is very much reason for Magical BLU's, just this allows us to be versatile at the drop of a hat on the field, rather then taking the time to fool around with game mechanics to deal magical damage on a BLU.
