Modify Armor Lock.
• Sticky grenade will not be nullified if you use Armor Lock after being stuck.
• Damage received while in Armor Lock is transferred to remaining Armor Ability energy.

so whats the point of armor lock with this change?

To not be overpowered, annoying BS.

The new Armor lock will be like rechargable very temporary overshield which is much more sensable.
