[Mechanic] "Meditation": X second "out of combat" rule -> +Y% mana regen.

Could we get a X second "out of combat" rule -> Y% increased mana regen mechanic on the mages?

With the regen% -> max mana planned on the 6.9, I feel that we're losing a lot of sustain. I understand the need to have an exhaustible resource in fights, but if you haven't

• attacked
• casted
• been hit

in the last X seconds, then could we get a boost, at least for the farming?
