Legendary powers that have damage numbers need to scale off your stats like skills do. There are so many cool powers that dont work just cuz their damage numbers are 2-10k damage when a lot of core skills are doing 50k+. A great example are all the leapquake items in the game that make leap and ground slam drop earthquakes but they only do maybe 2-4kover 4 secs. 90% of these style of leggos cant be played with until their damage is either giga buffed or make them scale off your stats.
