I already explained my reasoning behind needing ballad in t8 in the earlier pages, we are talking about something completely different. Not to mention I don't need ballad at all in t9 and can heal it comfortable. But again, we're talking about something entirely different.
Because if your healers know how to heal efficient
And letting bards center their fight around a single healer is a really, really bad choice. They shouldn't need to center their fight around anyone, they SHOULD be able to react to everything that could happen and they won't be able to do that if they need to focus their fight/rotation w/e around a single person.

Edit: Oh and working strategy != efficient
