As I just mentioned in my PTR feedback I feel like the intention of these charms to add build diversity is great but I don’t like having to find a rare item to make a build viable in hell. Finding a rare item should make an already viable build stronger.
I mostly play self found characters so if I wanted to play a new fire only build character from lvl 1 to 99 I’d get stuck at the beginning of hell until I find the correct sunder charm or I’d have to play some other build first to get through hell and find the charm that lets me play the character I really wanted to in the first place. That doesn’t really feel like you’re adding much diversity to viable builds to play, nor do I have the time for this especially in a 4 month time period.
Now if those charms can be obtained from nightmare terror zones then I could farm those even with new builds because nightmare doesn’t have the amount of immune monsters like hell does. Then at least I’d be playing the character build I wanted to try out from the get go.
