Halo 4 Flood Mode Analysis

Before Halo 4 released I noted something that I really wanted to play and it was Flood Mode.Now I play it and I think to myself what is this? Now im not saying its that bad but since its going to be a replacement to infection it should resemble just like infection only the so-called infected should have a model of a flood.What I dislike about this gem mode is the lack of freedom it has to customizing your gametypes and im a forger who loves making infection maps.What they should do is allow you to customize the loadouts instead of just having shotguns and magnums and allow you to change the survivors color instead of having that Bio-chemical -Yoink- green and allow the flood to hold weapons rather than there Scratch-my-back claw it would make sense too because in previous Halo games the flood did use Covenant,Forerunner,and UNSC weapons so please make it happen thank you
