I would like to make an important suggestion, which is actually a bug (kind of).
When we try to use a healing or buffing skill with a dead mob selected, or an npc, or an ore lode, or lots of other things, the skill refuses to play saying something like "invalid target". That's so easy to fix. If the skill can be applied to me and you reach that error message, then just apply it to me! So simple, and removes a lot of klunkiness. Why would I be trying to buff a corpse or a bush?
The other thing is starting an induction, and failing it only at the very end, because your attunement in the meantime has dropped to below the required level. So frustrating! There are several ways to fix this:
1) Abort the induction at the instant the attunement drops below the required level, and save us the pain of waiting.
2) Be nice and consider that the attunement requirement is applies to the moment you click the skill only, not also when the induction ends. That makes sense. The induction is part of the skill, after all.
If you can get this done for RoI, we would be very happy indeed!

And think of the poor loremasters too who have exactly the same problem when the mob they're targeting dies during the induction (we have that problem too, btw).
