Not old enough to realize that on forums you have to use correct spelling. Also if you read this don't give us the "but this way is afaster in typing lol"

I've heard that way to many times.

As for the energy sword for chieftans I don't know. Maybe but it'll get destroyed when dropped just like the elites energy sword. As for the Brutes being damage sponges. Remember CMT doesn't copy Halo directly so having one of the more annoying aspects about brutes in Halo 2 just doesn't sound like something they would do......
