Nerf healing power scaling for specs that you don't want running menders.
I really don't see how this amulet nonsense is even under consideration. At launch we had clerics amulet, settlers, and others in a meta that was still more balanced and fun than it is now.
You need to make some decisions on how you want the game to be played, and balance to that ideal rather than this whack a mole system that just takes us from one op fotm class to the next. You remove menders and what will you get? Another meta comp and a smaller playerbase.
