Kunark Clickies

[geniusi]

I was in a group last night and a warrior told me he was unable to use his str buff from cobalt boots on anyone else as it was self only. I know that on my rogue, I can click all my buffs onto other people. Is this limited to certain pieces/certain spells? Or are they all pretty much clickable onto others? Seems strange it would be limited like that. Thanks!
