@podpeople Sorry, i'm a little drunk, but with your maths there, i'm trading in 1200 badges to get three frost items; 300 of which were already frost badges, so i could have bought those items and still had frosts leftover.
let me put it another way. i have 300 frost badges and 900 triumph badges. i use those frost badges to buy three items worth 95 frost badges each, leaving me with 15 frost badges and 900 triumph badges. i then get those badges converted into justice points, which leaves me with 2516 justice points, which i can then use to buy another two items that are currently worth 95 frost badges. So by spending the frosts BEFORE conversion i can get FIVE items worth 95 frost badges or equivalent, and by spending them AFTER i can get three. Seems to me like youre much better off buying frost gear now, if thats all youre interested in.
However, i think youre right about being able to buy level 85 gear with those points, meaning that you'll have a handy lead on some nice gear at 85, rather than some awesome level 80 purples that youre going to replace in one level with greens anyway.
