I was thinking, and I've probably brought this up before...

It might be interesting to have a concept of "pots" (or better name), which are sort of like an objective in many ways. There might be an hourly/daily attacking pot, and you fill it by attacking. There would be multiple milestones and each time you cross one, you'd get a reward of some sort.

The pots could have different timescales. Some could be for your whole guild (raiding pot?) - in fact, there could even be global game-wide pots that all players can contribute to, and if you push it over the edge, it unlocks bonus content / rewards for a while afterwards.

Perhaps it unlocks a special map you can visit, or repopulates speciality store items, etc.

The possibilities are endless. What do you think? Any ideas related to this?

Edit: one factor to consider is timezones, so perhaps they should be looser, with multi-day resets. They could "decay" slightly every hour if there's been no progress, so you have to push through that. Just an idea.
