Lifebloom was supposed to get nerfed, but Blizzard didn't want to screw up PvE healing. I hope I have a solution.
Reduce the +healing benefit of instant casts by at least 50%. Make them really weak. To maintain raid healing output, buff heals with a cast time. The combination of these should keep raid healing output and efficiency the same. In PvP it will foce druids to make a harder choice between mobility and efficiency/output. Staying still makes them better at healing, but also vulnerable to interrupts and damage, just like any other healer. Going mobile gives protection, but with lost healing.
MMO gamers, go ahead and complain.
