I have to disagree. A stick is a stick. Armor Lock should only protect you from outside hazards. Once stuck, the grenade is attached. If Armor Lock could pull a sticky grenade off then sticky grenades would be pointless to use. The stickies would be more of a hazard to yourself and allies around you than your enemies. I also feel that if you end up being the unlucky receiver of a sticky and decide to Armor Lock, the blast should be contained within your shields. It would incorporate more strategy into using Armor Lock. Think about it, if you're stuck within a short distance of your allies a quick Armor Lock could turn a triple kill into a single.
