So, from what I read is that the only way that CH could/should be taken out is if it is replaced by other spells that would do the same trick, just in a different way (combo of HoT and "other" heals). Why would the dev group here waste their time making an overly intricate heal system that would be usable for raids, spending weeks or (likely) months balancing it, only to end up with the same end result as you get with CH? Wow, it might be interesting to figure out a new way to raid, OR, it might be extremely annoying that you are wiping on a mob you used to roll right over on your way to the next in the midst of figuring it out. Sounds like a gi-normous waste of time.
and to remain true to the original subject of the thread, I also, as a warrior, hardly ever use my HoT spells.
