i finally got a fragment champion for both off and def BGs.  One 5 and the other 4, i been using them both for the last 2 months or so.  I used them both on the marrannon bg 2 weeks ago. i used them both on my league last tower event. I went to use them both for this week's battlegrounds and my off  frag champions wsasnt there. instead i had 4 defensive fragment champion that i dont even recall having/getting. the defensive champion has the same stats as my off frag champion.  i was instruction to post my concern here in the forum. it took me 8-9 months of trying to get them both. 

trying to understand this.
