"Terror" penalty.

I think it is unlikely to be introduced on existing worlds, they are reluctant to change existing world setups.

You are basically describing the morale system being altered, where the morale reduction gets greater the more attacks that take place.

I hate forgotten attack servers but the idea of forgotten hitting back if you don't kill or don't kill within a set reasonable number of attacks is a good idea but only for the sake of keeping map clean ;-) Would save burning camps etc and stop guys hitting targets too high for their level to finish ;-)

yep, but this should influence those worlds too... there are "stuck" players out there... it should serve as an incentive on "how do i become more efficient" thingy...

oh... and also, players that don't finish their target in max 24 hrs should have a visit from a fortress unit (with a level more or less the fortress has/will have).

Changing the way the morale works on new morale worlds may be possible. Having a super charged attack if you don't finish a target within a set time is an interesting idea (for me, at least). Maybe the super charging should be for the first band of the attack by the forgotten and set at 10 levels above the regular units. That way there is still a slim chance to survive the attack if you have a good defence and defence bonus.
