Just wanted to post a quick reminder of the dispel changes. Every healing class has the capability to remove harmful magic effects from friendly targets. You may have to talent into it somewhere, but it is possible.
In encounters going forward, any highly important buffs that need to be removed will come in the form of magic. Other negative debuffs will annoy the raid or make life a little more difficult, but they will not get to the point where the encounter becomes literally impossible to do.
For example, if Lich King were to become a Cataclysm encounter, Necrotic Plague would be a magical ability so that any healing class could remove it.
Druids
Remove Corruption – Removes a curse and a poison (Removing magic requires the Nature’s Cure talent).
Paladins
Cleanse – Removes a disease and a poison (Removing magic requires the Sacred Cleansing talent).
Note: Protection and retribution paladins cannot cleanse remove magic.
Priests
Dispel Magic – Removes 2 harmful spells from allies or 2 buff spells from enemies.
Cure Disease – Removes a disease.
Note: Shadow priests cannot remove diseases in Shadowform but can still dispel. No change to Body and Soul. It will still remove a poison if you Cure Disease yourself only (Won’t work on others).
Shamans
Purge – Removes 2 buff spells from enemies.
Cleanse Spirit – Removes a curse (Removing magic requires the Improved Cleanse Spirit talent)
Note: Disease and poison removal abilities have been removed. Yes, that includes the totems.
Mages, warriors, hunters and warlocks (Fel Hunter) have no changes to their dispel mechanics.
Actually, come to think of it, Necrotic Plague is still going to be a disease in post 4.0.1. That means the only way to remove it is by having a priest or a holy paladin in the raid.
Oh dear.
Hopefully, it’ll be hot fixed so that it becomes a magic effect or something. Unless they don’t expect anyone to raid past 4.0.1. Right?
