In the long term, advisor units need a rework anyway because they aren't viable for people with level 40 legendary gear and BiS macro advisors for turtling into cav-seige-priest-one of either ranged-aggressive towers and forts (the one true composition for PvE). I'd say then this means the devs are best off putting everything regarding them off til they can focus on them and address them on all fronts (giving Norse and Babylonians new ones OR letting all factions use all unit advisors, removing the stats advisor vs unit advisor issue through letting them take up slots in a different system, addressing the unit scalings per level/giving them item slots?)
