-		Used in SPA 154 and SPA 209 to specifically dispel only beneficial or only detrimental spells.
-		Formula derived from live parsing.
-		Baseline chance is 'base' / 10, (ie. 950/10 = 95%)
-		Chance receives a penality of 0.5% per level, for each level the 'caster of the buff/debuff' is above the caster of the dispel.
-		There is no bonus percent chance for trying to dispel buff/debuffs cast by mobs lower level than you.
-
-		Ie. Lv 69 Shaman Casts 'Pure Spirit' which has 95% chance to remove deterimental on a debuff cast by a level 85 raid mob. 85-69= 16, 
-		then 16 x 0.5 = 8% penality, thus actual chance to remove is going to be 95-8 = 87%
