If they make any changes to healing, just adjust to it. It will not be a night and day difference anyway.
All you will need to do is...
1: possibly put more survival into your build if you were not already. Make sure your gear has enhancements as much as possible to help.
2: use line of sight more, unless you are already in which case this does not apply to ya
3: make sure you have people watching your back, which you should be doing anyway but if not this is a good thing to learn.
Even if they make a change, we'll be fine. The same bad players who complain about healing will still not be able to kill you anyway so the game play will not truly change drastically.
If they lower healing some, you can find ways to boost it back up! That is where adjusting your stats can help, maybe looking at your build differently etc...
