Ryze with 3000 mana and an Athene's is regenerating 30 mana per second in my proposed system (ish) - but his ability costs are all easily 120 each. He's still going to run out. Realistically, even on live, Ryze doesn't run out of mana mid-late game (through combination of buffs and items). This new system would only really effect champions like Maokai who just stop functioning after 10 seconds of combat, regardless of whether they invest money.

But perhaps you're right - but I got frustrated in a game where I was constantly out of mana, invested heavily in items to help, and it never fixed my problem. Mana regeneration feels like a dead-end stat and I don't think that is healthy. Buying any stat should have a return - especially since the decent mana regen items are dedicated mana-regen items. Champions who are permanently silenced at 0 mana are always permanently silenced at 0 mana, regardless of how much money they invest in mana or mana regen (such as Maokai). Even if my system goes against the current philosophy, I can't help but see that as a good thing - because I think the current philosophy is discriminate toward mana regen versus aother stats.
