Easy Non synchronized AI?

I have a feeling this question has been asked before but ill shoot anyway. A minor but mildly annoying problem I face with the adversaries in my game is that if there are more than one of the same type of enemies in the radius of the player, then their AI seems to act in tandem with each other, attacking at the same time and moving at the same time as well. This may be attributed to the fact that most of their actions are timer based (i.e. every 3 seconds, specific type of enemy moves left or right). Is there a way to make the enemies movements seem more natural and actually give them a mind of their own instead of a "hive mind" if you will?

The issue here is the Every 3 Seconds event. You can use a random value for this. To do this you would need to use one of the Enemy's Alterable Values.

Enemy is within range of Player
+Altable Value A of Enemy < 1
>Set Alterable Value A of Enemy to random(4)+2

Every 1 second
>Subtract 1 from Alterable Value A of Enemy.

Alterable Value A of Enemy = 1
>Attack the Player.
>Set Alterable Value A of Enemy to 0.
