Less Luck.

I stated in a different thread that it could be possible to split the Hero Deck between each corner of the board and the Hero only draws from the Deck that corresponds to the L-Shaped board they are currently on. The Discard piles could be split as well or combined into one Discard pile.
Of course, this presents the problem of drawing cards while on the center board. Or if the zombies force to discard cards from the Hero Deck and possibly winning due to last Hero Card discarded.

The last Hero Card discarded rule has become an old relic of a rule anyways as it is hardly ever needed. Could possibly make it to where the Zombies win if 2 or 3 Hero Decks are depleted. But you might as well just discard the rule entirely.
The Zombie cards that discard cards from the Hero Deck could be chosen with Zombie's Choice.
Hero's can have Hero's Choice when drawing from Hero Deck while on Center Board.
All in All, This diminishes the Luck factor by giving you access to more of the cards since they are split between the L Boards.
You cannot search a building on a L Board that has it's Hero Deck depleted.
