Well that was fun! Gave me 82 paragon levels (300 to 382)
It gave me 118 legendarys.... not including those i had to gamble.
Each grift was roughly about 3 minutes... so in about 40-45 minutes we completed all 13.
I have no idea about fairness of price... been out of d3 and off d2jsp for too long... but in my opinion it was well worth the money... gave me a significant boost after recovering from a bad loss early season.
