12.9.2013 "percent addition - o'rly!"

[OJaaaa]

fixed bonus application of certain "increases total amount by x%" buffs/talents/glyphs. the effective value of Multiplier is now computed by percent addition. single bonuses of each buff are now added together instead of multiplying.

however not all percent buffs are affected. only certain type. (108 SPELL_AURA_ADD_PCT_MODIFIER)

for example Frost DK has Glyph of Obliterate (+20% damage) and talent Annihilation (+45% damage) which are additive, while Frost Presence (+10% damage) remains unchanged.
now:
total_damage = damage * (1 + 0.2 + 0.45) * 1.1 = damage * 1.815
before:
total_damage = damage * 1.2 * 1.45 * 1.1 = damage * 1.914

damage of some abilities will be therefore lower.
