Armor abilities and bloom are more of a frustrating addition than they are fun. I complain more about them then I actually cheer out of joy. And even when I use them succesfully it feels cheap.
Most people in my friendslist exhibit similar behaviour. Some of the more hardcore players even went so far as to sell Halo Reach...just because the game feels so random now.

My point is that I don't want to see the original Halo fucked up in a similar way. Halo 1 + Bloom + Armor Abilities = disgusting.
