I really want to make bard but...

[Orionsaight]

My scroll through NPCs target key doesn't always work right.
To change targets, the first time it takes two times pressing the key to switch to another target. Sometimes it doesn't. I assume bards need to do this in order to mez other targets. I think for the most part I will be ok because most mobs don't stack perfectly. What do you all think? Do u think I could play a bard with a semi-functional scroll NPC key?
