The whole idea of a holy priest is that we can fulfil different roles decently depending on the needs of the raid at that time. However, it would be far too much for us to be able to do everything like that without any form of sacrifice. As it stands, we're in a pretty damned good place right now, because the only thing we miss out on when committing to a chakra is the bonuses of the other chakra.
fg you're against chakra because it locks you into a specific set of bonuses for 30 seconds, then you're against intelligent choice, but a choice that ultimately won't break you. And if you're against intelligent choice that carries a bit of weight but not the entire status of your class, then that says a lot about you and your argument, and any further comment is futile.
