So I believe gaining emperorship within a campaign should be reevaluated, do to the fact of those or 1 individual constantly gaining emperorship, through any means including cheating.
It should be once you have obtained emperorship within the campaign you should not be allowed to obtain it again, until next campaign. Instead the 2nd runner up will obtain emperorship and it will just go down the list of the top players, also as being emperor you should make it were you no longer can collect AP, or only receive AP at a reduced rate. I believe this will bring in more competitiveness and more diversity as to who is emporship.
There are players who may potentially account share, which results in them constantly gaining emperorship.
Any positive input is much appreciated.
