I recently start to spend a bit time checking forums, and read a couple balance complaints in RM, DM or TG revolving mostly team bonuses.
In AOE2 there is that “all tech” option that enables full tech tree for all civs but takes out all civ bonuses, team bonuses, team units and such, leaving only UU as the only unit unique to civilisation.
If people are complaining about civ bonuses a lot, what about rolling a season where players play RM, DM or TG using that “all tech” option? Maybe players will have some new idea on how they approach their civs without those regular bonuses. And since every civ is very similar, maybe some will have some new ideas regarding balance changes.
Edit: “Season” is a concept borrowed from Starcraft II when ladder match map pool changes. For AOEII DE, this would be the period when ranked map pool updates to a new set.
