Should Cleric Stance be disabled in party instances?

[Lmcgyver]

I feel like I am being misunderstood here, so let me try and make it clear; my stance is that healer DPS is fine as long as it does not interfere with the primary objective of keeping the party alive and clearing the content.

-Snip-

If a healer is not confident in their ability to deal damage whilst keeping the party alive, then they should not be forced to do so. Sure, encourage them to do it, but never force them.
This is nothing to do with dodging/mitigation (that's a part of any role), tanks dealing damage (that's a natural part of keeping enmity) or with DPS meeting a 'quota' (their job is to kill the enemy as fast as they can; "dealing 'x' damage" is 100% of the health of all enemies). Healers and tanks dealing additional damage should be an appreciated bonus, and not a demanded requirement (except in savage raiding, where every bit counts; but for regular instances, it really doesn't matter).

EDIT: Anyway, I originally posted here in response to someone implying that it was not a healer's primary role to heal (because it is their primary role to heal). I did not come here to have an argument about whether or not a healer should be expected to DPS with arbitrary comparisons to what tanks and DPS are expected to be doing. If you think healers are required to DPS, well, I can't be bothered arguing with a difference of opinion any longer, especially seeing as it is not directly related to the topic at hand (namely disabling cleric stance in duties... which I vehemently disagree with).
