are mana regen boots really that important? At a certain point in the game, mana regen becomes kinda useless compared to flat mana or penetration, and the amount that boots would give you to be balanced would probably be just over a fairy charm. not really too usefull in the longrun. what they should do is add a small mana regen aspect to lucidity boots.

As for bezerkers grieves. there is really no way to add a second effect without being broken unless it is something like health regen aspect. but even that would make adc's and junglers like nocturne a little too strong.
