Something you should not forget about healers/healing is, that you should Play the role from a safe distance if possible. Most Pet healing abilities are Bound to a limited area. So do you really want an Electricity or Nature heal for example stay within a few meters - running behind the tank as he kites? Or even funnier Scenario, let the Tank kite around the heal as he Spams his pet heal in order to keep Brick alive? So i'd say Bricks issues are on both Ends. A solution could be, that all Healing done to you as an Earth Tank is copied on your Brick aswell. Since the big chunks of Damage are destroying shields and hitting your Health, your Brick will lose Health aswell (unless you used Fortify Golem). This would automatically help healers to heal Brick with all of their abilities when neccesary. This would not help if the Golem sits in an AoE but you are at Full Health because you used a Shield for example. That way it would still synergize nicely with the specialized Pet healing abilities and wont be too strong to outright replace the Jackhammer playstyle.
