Pre-Purchase Mad Max

I don't think that's a good criteria. The state of a game is the developer's business. Middle Earth Shadow of Mordor was a very well optimized game and more or less bug-free, right from release. You can watch Total Biscuit's video if you don't believe me. It too was a triple A game published by Warner Bros.and there were little to no problems with it technically. So what's the difference between it and those two game you mentioned? It was made by Monolith, a company that is not in the habit of insulting paying customers by releasing games in horrible states like Netherrealm and Rocksteady seem to do lately... So the most you can accuse Warner Brothers of is not holding a tight leash on their business partners or being greedy douche-bags that don't actually care about the game's functionality on release, only about the piles of cash that they'll get from it.

So if the game's developer, Avalanche is one you feel you can trust, based on past history or whatever, I don't think you should have any concerns for the game turning into an Arkham Knight proportions fiasco. I still wouldn't recommend you to pre-order it, cause pre-orders, in general, are a stupid concept, but there you go...
