I completely agree with Roger's opinion on that, such major changes should be optional
These changes will bring imbalance in the match ups of existing army lists in the same manner each new edition of warhammer 40k brings
Since our aim as a community is not to sell minis or books in the thousands like the fantasy codexes, we should leave room for options in the army list
Last but not least, i am still not convinced that the changes in DC units did not came from players that pationately want to play less impetuous units to save cards for later manoveuring, that could simply exclude this units from their army lists (in most of them if not all, none of the units that changed were not compulsory)
They could simply take only one unit of cretan archers, or illyrians & hillmen instead of thracians, instead they are pushing on the wrong direction to have universal changes that for me are creating more problems in the community than solving them
