Why give the ability to lockout classes for Raids?

This community is really quite odd, isn't it? I can't think of any other game where the community routinely does not want the #1 parsing DPSer in their groups. It's mind boggling. All you can really do is be persistent or start your own groups. Perhaps one day the community will drop this ridiculous mindset.

BLM have the potential to be highest dpsers.
You actually have to be good at it to get there though - rolling a BLM isn't an instant 'i win' button and the chasm between a competent BLM and one that isn't is seen on a daily basis.
