Put a cap on resources (mostly for mana)
I think it is common to run into a situation where you have such a ridiculously high amount of a resource, it becomes completely irrelevant. This is because it is hard to balance how many units of that resource are generated each turn. Too little and it takes forever to do anything. Too much, and it pretty quickly becomes a vast hoard.
To get around this, and to create another level of strategic depth, we need to introduce storage capacity. This can be managed and increased throughout the game as necessary (at a cost, of course).
I think this is the most important for magic. I would really like to see the mana generation increased significantly. This would allow for more enchantments to be cast and a restocking of mana that doesn't crawl. It would also create a use it or lose it incentive to cast magic as opposed to hoarding it for a single unstoppable disgorging upon your enemies. This would make battles more enjoyable, because there would be a reasonable limit on how much you can cast. Right now, you usually have none or more than you can use.
Mana storage could be increased by adding more channelers, shards, magical buildings and cities.
This could also be a good dynamic for materials. It seems in the early game you never have enough, but you usually go through a period of little use where your hoard becomes bottomless.
Any thoughts?
