I support the idea of adding threat generation to AP Delta. I prefer to fly cruisers, and while they can take a hit with more grace than an escort, that ability is completely wasted when the enemy isn't even shooting at you. So your choices to maximize a cruiser's capabilities are then either

1.) Dump points into Threat Control (NOT a cheap skill) and be forced to spend a bucket of zen to respec every time you want to fly anything that isn't a cruiser.

or

2.) Become a heal-barge so you can dump hitpoints into whatever glass cannon is doing enough damage to draw all the aggro.

Neither approach is... very nice.

Simply adding strong threat generation and/or "taunt" power to delta lets players chose to become the enemy's primary target when they want, in which ship they want. Some players have brought up interesting uses for Delta like escorting freighters, but ultimately I think we have to consider most likely usage cases here: patterns alpha, beta and omega are extremely useful and see widespread use while the support for pattern delta revolves around "Well it's useful in that one mission where..."

It also seems a little silly to rely on Delta to debuff enemies when you already have an attack pattern that does exactly that, except you can use it more often and it affects who you want it to affect immediately.
