Flood's and Universe's Warhammer 40k fanatic and the one who knows much about it.
I also like House Stark and winter, hurr.
Human/Flood war would be in my opinion better, since Forerunner's weapons are just simply so powerfull.
It still could be lots of fun to hack way through dozens of floods as forerunner and then face somekinda boss battle with special flood form.
