I have noticed an increasing tendency to use an ability against a solo boss and get the in game message that it has no effect or the boss is too powerful (although on my level).
I am NB (hear me roar) and this has impacted on pretty much every stun or other ability that provides ways to hobble them before you get slammed, essentially the things needed to stay alive.
How common is this? Does it happen with talons or other similar control abilities from other classes?
Certainly has a negative impact on a battle when none of your abilities work on the target...
