lockdown is not a map. Lockdown is an option of something that you can have instead of invis, sprint or jet pack. When you sustain damage and are about to die, you simply press a button and you become indestructable for about 10 seconds. I got tired of people using it when they have a shotgun so when they come out of lockdown, you go for a beat down and they just shot gun you.
Actually, Lockdown is a map. It's a custom FFA map of Construct on H3.
What you're thinking of is Armor Lock. Some playlists won't even allow this AA. For example, in Slayer Pro you can only have Sprint, which is likely to be the case for MLG too. These Armor Abilities will just widen the skill gap anyway. The reason you don't like it is because it's new and you don't know how to react to someone using it. Hint: get behind them.
Plus, the amount of customisation in Customs is unbelievable. You can alter the game to exactly your preference.
