I usually roll with the same people so what I'm looking for is High Defence, High Taunt. I like Ice armor because it slows all the mobs around me, and it seems decent overall. Ice/Mace was my main back in the day but I can see the benefits of going DM.
As far as Primary/Secondary what fits the bill for highest Defence + Taunt I'm willing to try new combinations that best fit my group.
If I remember correctly you really can't Judge a tank on its Tankyness until level 20+ cause with my Ice/Mace Tank only level 12 I'm soloing all my missions to get caught up to my friends without very much health loss. Honestly, I don't believe I use any Healing inspiration other than to cycle them out for more defense, dmg, and endurance.
