I'm not 100% thrilled at the re-arrangement of cleansing, either, but assuming that Blizz is also going to be designing encounters with a new cleansing system in mind, it really should be a general positive.
I like the GENERAL idea of cleansing being more of a strategic decision as a healer - higher cost but less frequency, more meaning behind the decision to heal vs. dispel. As terrific as cleansing totem is, it IS pretty "mindless" in some ways (so is abolish poison, for Droods, to a lesser extent.)
Basically, I'm reserving judgment on the principal that the changes are also contingent on encounter and boss design. The GENERAL theme, seems to be in line with Blizz's stated goal - less spammy, more strategic healing. I endorse this, contingent on good execution from the powers that be, of course
