I didn't mind Armor Lock. I never used it, but liked it when others did. It's an easy kill.
A well-timed grenade or waiting for the AL to reduce was simple enough. It would only save that person from dying for a few moments. I can't recall a time when I saw someone use Armor Lock and got away without dying afterwards.
there was a few videos of FFA slayer were a dude took 6 guys out in that tower on pinnacle in a file share he was useing the DMR and AL in CQC and tore them a new one if used correct it can be a good tool but its not meant to be used as a last resort when your shields are down it has better uses
