New found mana issues

With the recent changes to , in particular whereas kill would refund mana, there has been issues arising running OOM. Before, used to remedy that, but with that now chanced your forced to rely on flat mana, which of course, runs out quickly. For some this is a much bigger issue than other, but starting full mana in a fight, I can be easy to run oom during said fight. Late game this affect can be mitigated with a large mana pool, but for some, that isn't always a solution as they tend to drop off late game. has been an excellent "crutch" if you will for helping preventing lanning phases whereas both parties run oom, there are also runes to further assist. But its making so these runes feel required, rather than a choice. I mean you can always push lanes without mana, but unless you've got an ace, usually a bad idea. Anyways as late game approaches, and you've finished your you no longer have any real Regen unless you runes the runes for it, making it harder to stick around after fights for risk of running oom. Mages need mana Regen, and the current item set doesn't provide that anymore.
