Even though Bards consider the RoD debuff trasnfer from Brd to War a nerf, I never really saw many bards use it unless asked. In all honesty, the only time i saw bards use it consistantly is in turn 4 (with a large group of mobs) with the large groups and dreads. Now, since war will have it he won't have to bother the bard to get it and the bard can concentrate on DPS more? The other tuns in coil won't matter so much since you may now have a war with you attacking the target and applying the debuff (Excluding T1 for Main/Offtank which ever one isn't the war.)

Adding a evasion debuff isn't bad though. As people are getting their gear to hit/reach accuracy caps, this can be thrown down to help with connecting attacks until your group is properly geared. Just a thought though, I know most people don't like nerfs.
