Assuming they return for the next instalment (as they're pretty key to the overarching storyline now in my opinion), I'm hoping 343i expand upon the Flood and make them a bit more interesting as enemies.

It's stated a few times in the games/books that the Flood gain intelligence as they gather bodies and start forming a Gravemind etc. etc.

So - what do people think about curved Flood AI for Halo 5?

I.e. - you find 1 combat form on its own. It's behaviour is dictated solely by its base desire (to absorb you into the Flood) - it charges you looking to get into CQC.

Next scenario - you find multiple combat forms, infection forms etc. - perhaps this time, the infection forms charge you whilst the combat forms hang back, perhaps some run in etc. The combat forms will still be pretty careless - perhaps some won't have the advanced intelligence to even reload their weapons.

Taking it on even further, if the battle starts moving you closer to a Gravemind (or Proto) then the Flood start getting more intelligent as well - perhaps the combat forms start taking cover when you approach, picking up new weapons based on their surroundings, moving to higher ground etc.

Thoughts?

Basically - I'm bored of fighting an enemy that hasn't really become any more fun to fight since Halo 1.
