Short and sweet.
HAND PICK EXPERTS!!!!!!!!!!!!!!
Sorry for the large font der, but seriously.
Editing powers shouldn't come so easy. Everyone and another 9001 users have suggested this. It seems necessary to get rid of points getting you privileges. You said it yourself, it isn't a matter of deserving, but need.
Also, suggested by trachy some time ago, if two Mods agree let them make an Expert. Otherwise Mods getting Promoting privileges is stupid. You may have noticed, trachy made myself and UberPwnage Experts recently. So why do they have the power if you didn't agree?
Mods + Editors feel free to edit this with other points about it.
