I think that armor abilities were a great addition to Halo. Now my favorite is armor lock (I know some of you might think it is noobish), but sometimes people actually have a strategy to go along with the armor ability and that makes it more challenging than annoying. And I don't always automatically choose armor lock. It depends on the map, game type, tier, and sometimes opponents. The noobs that spam armor lock are really annoying, but if you become impatient then chances are they will get you. If you take your time, keep your space, and time your grenades correctly you will have no problem.
