The story is severly lacking. The ending is absolute garbage with no exciting end or closure. The AI either knows exactly where you are or not at all. Your ally's AI is just as bad. The stealth Fang for Hire is not stealthy in the slightest and was always spotted first. Certain missions require you to free civilians which can take hours if they don't spawn / the cultists kill them before you can even engage them. The skill tree is super expensive for the small rewards they offer.

Game play wise, it's a great game, visually it looks great, but too many downsides. Chances are they'll release pointless DLC or the ending will be resolved in a DLC. If that's the case then that's just a joke on Ubisofts behalf.
