Your point is moot since the core of what you are trying to argue against is that "holy could deal with the fight at lower gear levels, but since disc has been able to catch up it can also do it too." That doesn't make for a sound argument. You would do well to accept the reality that both specs are great, but that holy does, indeed, have more "oomph" than disc. In that sense, holy is, indeed, a better healer in the purest sense of the word. You are worrying too much about some debate that I don't personally take part in. I understand both specs have merit and place, and gladly admit disc looks better on certain damage patterns. That isn't to say holy couldn't heal those patterns, and it certainly has no bearing on which spec is "better." Disc excels at what it does (absorbs, effective health, mitigation) and holy excels at raw healing. This really isn't debatable.
