Parsing healing is and always has been pointless. Everquest 2's ACT plugin was one of the best parsers I've seen in any game in terms of informational breakdown (the eq2 log tells you damn near everything if you want all the details) and parsing healing was STILL pointless because the only things that matter are 'did you live' or 'did you die'. Just like parsing for DPS is meaningful if you want to eke every bit of possible damage out of your rotation, but even without a parser it's usually obvious if one DPS in the group is leaning back and hitting a 1-2-3 macro.
