Healer as a role seems to have very diminishing value the later in the game you go..to the point of current ultimates being cleared without a healer or even less than recommended.

I think healers should be given more of a support role philosophy.

Obviously damage is not strong or constant enough to warrant a lot of healing...and tanks have heals that are comparable to a healer.

Either give healer's more unique utility options, like haste, damage up, crit up, buff timer extensions etc.

or give enemies more debilitating statuses that only a healer can cure/mitigate.
