the mega blitz realm eras like 140 usually ends in 26-27 days with little to play for players with lesser points. I suggest the era should atleast be 35-40 days with all other features same , the repayment of loan is same as that in slow realm i.e 168 hours , so ther is really not enough room for taking and repaying loan besides few other features are same as the slow realms. Rest the speed of the realm is fine and all other things are good. Also if possible farm capacity of individual provinces should be little increased. My main suggestion is about making the era little longer , hope you consider it and agree with my suggestion. THANKS.
The duration of the era in mega blitz realm won't be prolonged, the rules stay the same. You can try playing it right after the restart to catch up with other players, or you can play blitz realms.
