My suggestion is the introduction of the new format:
War of the Ring Expanded FormatFrom my experience with LOTR TCG, rotation of the old cultures was a big reason many players left the game. Even now on Gemp, Expanded is one of the most popular formats.
However, it is undeniable, that with the inclusion of the poorly playtested editions like
Treachery and
Deceit and Age's End, both Standard and Expanded formats became badly broken. At this point, I am not interested in playing those formats, though a format with no rotation like Expanded is my natural preference.
So, like we have War of the Ring Standard, I suggest the introduction of War of the Ring Expanded format, with the X-list and the R-list that was current before The Hunters came out.
