New dragon changes on PBE:

From FF@20: Dragon Buff changes: [Might be more!]

Dragon's Might (2 stacks) changed to "Grants your attacks on turrets an additional firey burn over 2 seconds." from "+15% damage to towers and buildings." Dragon's Dominance (4 stacks) changed to "You take 30% less damage from turrets" from "+15% damage to Minions and Monsters

As if turrets weren't weak enough.
