There are no ‘healers’ in the game, so I am unsure what it is you want to be ‘fixed’. There was much discussion even before the game launched that players would never rely on others for healing, but primarily themselves.
Here is an article about healing in GW2:
Heal: Don’t belittle the SUPPORT role by calling it heal. Healing is the least dynamic kind of support there is. It is reactive instead of proactive. Healing is for when you are already losing. In Guild Wars 2 we prefer that you support your allies before they take a beating. Sure, there are some healing spells in Guild Wars 2, but they make up a small portion of the support lines that are spread throughout the professions. Other kinds of support include buffs, active defense, and cross-profession combinations.
For instance, an elementalist can support his allies by dropping down a ground-targeted healing rain that rejuvenates allies in an area. He might also use Windborne Speed to help them chase down a target or escape out of longbow range. A warrior might shout “On My Target” to help his allies do more damage to a marked enemy, or use his warhorn to “Call to Arms” which improves the armor of his allies for a short time.
We use our cross-profession combos to fill in the rest of our support. An elementalist can create a Firewall or Static Field to improve the ranged attacks of his allies. A warrior can carry a Banner of Wisdom around the battlefield to increase the power of his allies’ magical attacks. An elementalist might cast an ice spell to freeze enemies, but that same spell might give his allies Frost Armor to protect them from incoming attacks. When you boil it down, support is just the friendly way for players to work together to accomplish a shared goal.

Are you asking for the Developers to change the basic game design, and add healers?
