I know that in Crucible we will still be able too play with the old legendarys but that's not the problem the thing that I love to play the most is iron banner and I know I will find a few new guns in the taken king that I will like but I also want to use I'm old guns in iron banner too I also want to be able to use im old guns in the new raid too so that's why we need to be able to ascend the old guns too and of course I know I could just take the old guns too the new raid or iron banner but the problem there is it would be impossible to kill anything because of how big the gap between lvls is have you ever tried to take a lvl one gun into iron banner and try to kill someone that has a thorn or last word it is almost impossible man
