Not exactly true for orruk warclan . We already had separated releases for them , we never had any mixed release. Like they made a second wave exclusively made with Ironjawz models , or we had a battleforce and a vanguard exclusively made with kruleboyz.
they already had a dilemma about orruk warclan and releases . Having them separated won’t change the release fréquences for them but it wil’ be easier to collect them through the spearhead or battleforce specific boxes
