Yeah, this is what I was getting at on page four. I'm in support of this and agree it might be an idea to thrash it out between the community to get it in a workable form (ie easy to implement and effective for the job).
How about then this proposed idea of "self-buff to single-target party member enhancement transfer" is activated with TP rather than a JA with an unsatisfactory cooldown timer or an additional Charges system? That way it's still something you can do if you're back-line and not changing your staff (only a limited restriction for a single TP build), but encourages the quicker TP building performed whilst meleeing.
