The truth lies all in the cake. Just look at Mist Energy an Crystal Energy. What DOES it symbolize, and why do I respect and not hate the energy system anymore?
It all started after my head went thinking. The reason why OOO made energy so limited of use is because they tried to make energy look REALISTIC.
It wasn't all this "currency mumbo-jumbo", instead, Mist Energy is literally "natural energy", like us people get everyday. Think, you can't POSSIBLY complete all the missions with mist energy... in real life, that would be impossible, and you would simply get tired of it. Think of Spiral Knights as a job, you're a KNIGHT. Being a knight is your job; you're protecting Haven.
I mean, Spiral Knights is to escape to a world, where robots roam, with stunning clockwork backgrounds. Spiral Knights, is different if you think "outside-the-box". Mist Energy is your ENERGY. So, what is Crystal Energy?
I think of Crystal Energy (CE) as synthetic type of energy. You need to purchase Crystal Energy with crowns/real-world money, meaning that Crystal Energy in Spiral Knights is NOT NATURAL. So, crafting 3, 4, and 5* items requires more than your "natural" mist energy. OOO made crafting super-duper fast to do, just get the materials, weapon/gear, energy, and crowns, and you make your item. But in reality, it would take more than your energy. That's where Crystal Energy comes in to help. That's why Crystal Energy in Spiral Knights is SO TREASURED. Because, it basically is like, I don't know, say like, steroids or something (xD) in real life. I don't where i'm going with this, but the point is, DON'T THINK of Crystal Energy as you used to think. Don't think it's just a rip-off, and OOO just wants money. Don't think CE/ME is currency. Because it's not. It's time to tie games to the real world for once.
Ok then....
Um...
Alrighty...
I'll be leaving now...
