Seek Advice for RAF Boost

4) Heirlooms - Does the heirloom +XP actually stack with the 300% from RAF?

It stacks with multiplication. XP = (100% + modifiers) * (speed factor) Heirlooms, guild standard, xp potion, (and I think holidays) all count as modifiers. Rested and RAF are speed factors. It's possible to have (100% + 70%, 55% without guild standard) * (300%) = 510% with standard, 465% without (quests or don't have)

510% ? Wow... and I thought the 300% RAF were very fast leveling.
