"Give us good, compelling reasons to spend our mana at every stage of the game, and I guarantee that you will never feel like you have "too much" just "sitting around". It may also be helpful to have a mechanism by which really big, potent spells get cast using huge amounts of mana over several turns."
I think jpmcconnell put it eloquently:
"I actually like the fact that once you hit mana storage capacity you would have an incentive to use enchantments. Right now I have a tendency to hoard mana for that epic battle that just never comes. This would actually make me want to use some of the lower level enchantments."
This is how I see the current system playing out:
During times of peace, you hoard all your magic and gain a huge surplus. Maybe you would like to use some minor enchantments, or to imbue another channeler. But, you skip that to work on your rainy day fund. This is a time of very little magic use.
Then you go to war with another faction. On the first few fights, you are mana rich. Spells are raging, and you don't have enough action points to use it all. This is a time of intense magic use.
After some battles, your reserves are exhausted. Now it takes many turns just to generate enough mana for high level spells. You again in a time of very little maigc use.
Alternatively, there is a max supply but higher generation rates :
You start the game out with little use of magic, you build up your reserve. Once that is maxed out, you either deplete your generation with enchantments or you continuously cast spells to avoid capping out. You might try out some spells that normally you would skip. The important part is that magic use is plentiful.
When war comes, you make hard decisions over generation vs enchantments. During combat, you have access to a reasonable amounts of mana. Gone are the battles that are completely one sided magical eruptions.
When mana is used, it is replenished at a reasonable clip, depending on your gen. vs ench. tradeoffs. Magic use is still plentiful.
The second one sound better to me, but I am open to be persuaded otherwise.
