dunno but I painfully bought 1435 dragon cupcakes (30% MF) ONE BY ONE just for the MF attached to it, it would be a shame if all that hard work (and near broken mouse) were to be a waste of money and time and mouse.
Though Im glad we can now share all the MF across characters, right now im sitting at a comfortable 122% MF with my one and only set (zerker with everything else MF, including runes, ascended, infusions…)
Legendary SoloQ
I wouldn’t count on sharing that much MF accross all characters.
Their account wide 2-3% MF bonus’ from achivement points seem to be a pretty good indicator of what they think is a good reward.
If they think a +3% MF by the time you reach 5000 achievement points is anything to feel good about then they are once again out of touch with reality.
