Why are Healers allowed to be insanely overpowered?

[Buff_Archer]

exploit
[ik-sploit] Spell Syllables
verb (used with object)
1.
to utilize, especially for profit; turn to practical account:
to exploit a business opportunity.

Just to help clarify here's my bad attempt to define the OTHER way exploit is used within the context of a dictionary entry which I'm sure is where the mixup was:

noun (used with action)
2.
The other definition referring to a way to take advantage of a loophole in coding: Example- I used an Exploit in another MP game to get a 6/6/6/6/6 loadout instead of 6/6/6/4/2 which was the maximum allowed.

(I bet someone here knows what I'm talking about)
