[Gameplay] Greater Glyph of Scaling Mana Regeneration

Hello there, This is my first report and also my first thread so I hope I am doing things the right way. When I was looking at the runes I noticed that the Greater Glyph of Mana Regeneration gives 0.06 mana / 5 sec per level and is capped at 1.2 mana / 5 sec at level 18. But the math is not correct. 18 x 0.06 is supposed to be 1.04 mana / 5 sec at level 18.

So yeah, that's the bug I guess. Have a nice day.
