It can be very handy for people who are starting to play a new class. I used to prefer wowreforge but thats all messed up now. I use Mr Robot now and then but not for reforging. I like to use the extra features of what the best options are to use up valor and bonus rolls etc. Its easier to use mr robot than sit looking through dungeon journal to find out. +rep for this as it will no doubt help some that didn't know about it.
