The following are issues that I have run into while playing Oxyotl on Legendary IE. I don't know if these exist on other difficulty settings though.
- When confederating Naki: The horde growth panel still shows (doesn't disable it due to Oxyotl not using the mechanic). Naki cant move in ambush stance
- The Skink Chief only has 48 skill points, so when hitting level 50 there are 2 unspent points that have no where to go
- The "Hard" Sanctum spawns which spawn in Oxyotl's territory are not effected by: Rite of Sotek or Sanctum patrols
Overall it seems that the Sanctum mechanic spawns armies that are way too difficult early on in the campaign. When the first set of sanctum missions comes out around turn 12-15 a chaos army is spawned with all tier 3 units (Soul grinders, Jabbersythes, Blood thirsters, Great unclean ones, ect). It seems excessive this early on in the campaign. With this there are other issues. If you do kill the army Oxyotl gets a massive lvl boost of 5-6 lvls, jumping any other legendary lord in the area. Also these armies don't despawn, and reinforce each other should another one spawn. A simple fix would be to have these armies despawn when the sanctum mission timer is up.
