Midlane mages =/= Bottom lane mages

With the removal of mana pots from the game, Riot's trying to compensate it by increasing mana regen across the board on certain champions. That's a bad idea and here's why:

A midlane can get away with using a lot less mana in the laning phase than a support Lulu, because she can use her mana to efficiently clear waves. Similarly a midlaner can freely clear the lane with a W and a couple of autoattacks, and he never needs to interact with the enemy laner If he chooses to.

Meanwhile a bottom lane need to use a lot more mana to shield against abilities on much lower mana costs, and even ADC autoattacks. They also need to poke the enemy to keep their zones of control against hard engage tanks that threaten their adcs just by moving up

If Riot increases the mana regen of these champions by that much that midlaners will get just enough to make midlaners not mana starved, supports will suffer in bottom lane. Conversely If they decide to buff the mana regen of these champions enough that these bottom lane mages have enough, their midlane counterparts will be able to constantly spam their abilities and still have enough mana left for clearing the waves.

So what's the solution? Well they could keep mana pots, but seeing that's not an option in this case, I suggest buffing the regen of the starting items instead of buffing their base stats. Some buff for Doran's Ring mana regen and a little bit more for spellthief's edge and Coin basically.
