nice review but the "flood" wasn't a negative thing in my point of view...They were who made the story more interesting.

just my 2 cent ^^

When they ran into another halo they had to include the flood, or else the story wouldnt be consistant. I also think that the energy sword lasts a pretty long time considering its a 1 hit kill weapon. With a fully charged energy sword you get 10 covenant kills, and tons more with the flood. Actually I think you find the energy sword enough to not have to worry about how much it still has.
