Limit the number of raids you can join to 2 and increase the potential duration to 4 hrs on each. That way medium sized raids are still possible. Large raids would basically require either people raid during active game times to achieve better forum rollover or use unklanned alts to force forums to rollover on demand.

Keep the solo vanilla reward high (3 is probably a safe number but 5 might be fairly optimal) so that klanned alts serious have to consider unklanned players as a potential threat.

Limit the effectiveness of shields. It’s obvious that until they are nerfed domination is basically about ambuming the largest pile of shields and modests and deploying them in the last minutes of the round. Either make a card that randomly attacks another person’s card pile (thereby enabling people to whittle away at the leader’s card stack during the week). Under a system where we can attack another person’s cardpile there will be a group effort to keep the card leaders within striking distance.

Another option would be to limit the effectiveness of shields to just bumhole cards. Under this system you’d still see people make late rushes with modests but the current strategy of trying to ninja min scoops would be vulnerable to late counterattacks by your competitors.

I suspect a shield that we can declare as a shield vs bumholes or a shield vs shotguns, etc might be a bit hard to code thus I suspect we’d likely see flavored shields instead each of which would only protect against one type of attack. This would force people to evaluate the likelihood of each type of attack. Do you think you will be going for mins then load up with shotgun and destroyer shields. Are you going for max scoops then stock up on bumhole shields.
