A Syrian Rebel

In one of the game plays, it shows that a covenant squad passes by including grunts jackals and one elite. And the elite was going to attack you; which makes me wonder, is there a chance that we might fight the arbiter? Here's the gameplay. Start watching from the minute 3:38 And please feel free to give me your ideas.

I was wondering about it, why doesn't 343 Industries add brutes to the multiplayer? I know that it is kind of hard, but it is possible; it would be a new experience to the gameplay. Many people, say that brutes suck and they shouldn't be playable in Multiplayer; if you don't like it, don't choose it. What 343 industries could do is to make the brutes a little smaller in size and same shields (same as what they did to elites in Halo 3). And trust me 343 Industries many people would like it. Give me your ideas.
