Dispel Revamp

Dunno if it should go here but I'll stick it here anyway

I've seen it mentioned several places that the devs are wanting to revise the dispel system in general. From what I've gathered it seems as though they are relatively satisfied with defensive dispelling (dots and CC) but are looking to revamp offensive dispelling.

What I then propose is a classification on buffs as either a major or minor buff.

Major buffs would include spells such as

Mage armor
Ice Block
Fel armor
Demon Armor
Soul Link (debatable if it should be a magic effect again)
Inner Fire
Power Word: shield (per a talent in deep disc otherwise minor)
Divine Shield
Earth Shield
Hand of Protection (debatable)

Minor Buffs would be the remaining ones such as
Arcane Intellect
Power Word Fortitude
Prayer of Spirit
Thorns
Paladin Blessings
Mark of the wild
Detect Invisibility
Renew
Prayer of Mending
Rejuvenation
Regrowth (heal over time portion)
Lifebloom
Riptide (heal over time portion)
Hand of Freedom
Hand of Sacrifice

With the buffs classified as major or minor then most abilities that can dispel would only be able to remove minor buffs except for the priest ability mass dispel, and a similar spell given to shamans. Mass dispel and the shaman equivalent will need to cost a rather hefty chunk of mana to use and therefore not be able to cast excessively putting a steep price for the debilitating effects that dispelling the major buffs causes.
