Timber Peak and the Original LNOE to mix or not to mix?

[Fizzgaz]

I know I am late to the thread but I just stumbled across it. Mixing all the decks to me doesn't work if you need gasoline for the scenario and they end up at the bottom of a 200 strong pile it ruins the game. If you don't get close to the hero pile running out you lose that part of the strategy and the original games were designed with no upgrade no extra special uber weapons and I think introducing loads of stuff over powers the little games.
Just my opinion to shoot me, at least not in the head
