The problem is, the item in the Cartel Market specifically says it works for all characters in your legacy when you buy it. It doesn't. So, they need to either make it work for all characters. like it says, or change what the item says and refund my money, as I bought all 3 on my 50 who already had speeder I and II, just so I could unlock them on my other characters.
This is what happened to me, and I feel the same way.
