Has anyone calculated the mp5 equivalent of Spark of Hope? There is a pretty wicked trinket available in the AC with 60+ mp5 and an on equip spell power boost. I'm curious what it would take in terms of mp5 to replace Spark of Hope. Obviously the calculation is fight based and player based as the calculation would involve average casts per fight, but I figures someone far smarter than me has already done the math.
