Could you comment on the point you are trying to make ?
- Do you feel there are too many civs and ask which 5 civs should be removed in priority ?
- Or do you want to ask which civs are the least favorite of the playerbase (in whuch case you can look here: Favorite Civs poll and here: Favorite Civ Poll (updated))
- Or do you want to know which civs feel unfair to play against or to unbalanced between the different maps ?
- Or are you trying to argue against some civs not fitting aoe2 from a historical poimt of view ?
Without any reason on why to remove civs, I wouldnt remove any civ.
