Add back reforging. Seriously it was so goddamn useful. But make it more difficult to get done. Use much more weapon parts use maybe a few strange coins and a bunch of legendary marks. Also you shouldn't be able to do it all the time. 5 re-rolls per week. And you have to be rank 3 with gunsmith. I'm saying this because you know what, we need it. And the amount of ridiculously op exotics running around *cough* thorn, The Last Word, MIDA *cough* we need good legendaries to counter these terribly cheesy exotics!
