So when talking to some other members of the guild I found out that this information that I thought I didn't know because I am an idiot is actually unknown by many a seasoned player.
When filling the equipment spots for your legion it is important that you do not use the same gear as on your personal character if you use gear that has a proc. I will give a specific example of why this is so important.
Because I have more money than sense I own both the Drunken Angel and the Ninja Set from the new item expeditions. Even though the Drunken Angel set is more powerful and I could use it on both my personal character from my profile and also have my commander wear it this would result in a huge loss of potential damage.
If my character and my commander are wearing the same helm and I only have one of them then it will only proc once for bonus damage. so you will never get to procs from a single piece of equipment. If I had two Drunken Angel helm's in my inventory then the commander and I can both wear them and they could both have a chance to proc.
This is mentioned in the in game help page for the legion screen but I certainly didn't read it and most of those I have talked to had no idea about this rule either.
Any questions leave a comment here or on my wall in DotD.
