Well the problem from a raid standpoint is that means less gcds for damage spells like stone 4 and aero 3. Regen coupled with either a fairy or asylum meant that the whms could add damage. By gating the lilies behind cures, that means the main thing about the whm which is more dps than the other two healers which is to counter the fact that the other two 2 have more utility and the system of the lilies doesn't take advantage of that, as we have seen.
Heck I wouldn't be surprised if they tested it with the old build and realize how lacking it was but given how late in development they are, that this is just a band-aid but we need to see the patch notes on the 15th and the content before we make any final assumptions.
