Yeah that is one of the issues of 2h frost only have 1 type of runeforge vs dw frost having 2 types of rune forges, especially now with the new runes added (I do like the new options very much). I am guessing dw generates killing machine procs more often than 2h and I am sure there are other issues with balancing 2h frost and dw frost. Again I want to have faith that blizzard will do a better job this go around than before. No one is expecting perfect balance between dw frost, 2h frost and UH but it has to be better than when 2h frost was still a thing.
