Firstly, I would like to apologize if this suggestion had already be given previously. I'm new with Spiral Knights and I'm finding it enjoyable "at the moment." I said "at the moment" because though I find the game interesting the time-limitation due to ME 24hr regen speed is taking a bit off of that gusto to play it again.
On your business end--speeding up the ME Regen would keep more players playing... and more players playing would mean more players buying CE than usual.
So I'd like to take a shot on suggesting to cut down the ME regen to full in 1hr.
Just a suggestion anyway. But still... more power Spiral Knights!!!

Aaaaactually...
More players needing to buy CE to continue playing means more players buying CE.
It has been suggested strenuously and repeatedly, but it's unlikely to change in any significant way.
However, you'll soon find once you start making headway down that you'll get enough crowns to get comfortable amounts of energy for those extended sessions and never pay a dime anyway.
