Honestly, it depends on your secondary, your epic/patron if chosen, and how you slotted it. Alpha is also used to make up for any weaknesses in your build if there are anyway, as well as just adding to it if your build is already sufficient. Think of Alpha as a 'seventh' slot for all powers which are capable of having that enhancement placed in. So...
Agility primarily deals with increasing the power of Endurance and Recovery modifying abilities. Agility also increases Recharge, Defense and the speed of some Movement abilities.
Cardiac primarily deals with reducing Endurance costs. Cardiac also increases Range, Damage Resistance and some Status Effect durations.
Intuition primarily deals with increasing Hold Duration. It can also increase Defense DeDuff, Range, Confuse Duration, Taunt and Fly Speed.
Musculature primarily deals with increasing Damage. It also modifies Immobilization Duration, Defense Debuff, Endurance Modification, ToHit Debuff and Run Speed.
Nerve primarily deals with increasing Accuracy. It can also increase Hold Duration, Defence Buff, Confuse Duration, Taunt and Fly Speed.
Resilient primarily deals with increasing Damage Resistance. It can also increase Immobilize Duration, Taunt Effectiveness, Intangibility, Stun Duration and ToHit Debuffs.
Spiritual primarily deals with increasing Recharge Rate. It can also increase Stun Duration, Healing, ToHit Buff, Slow Movement and Jump.
Vigor primarily deals with increasing Heal Rate. It can also increase Accuracy, Endurance Cost, Fear Duration, Sleep Duration and Confusion Duration.
Look at the 'primarily' part and see what would benefit your Tanker most. Everything which follows depends on the tiered Alpha you have built.

Can anyone tell me the Alpha they are using for WP tanks? I am really torn. Basically, the biggest question I have is whether I should be slotting for more resistance or more defense. Can you give input, please?
