A trend I've noticed over the past several months is that people are moving away from Juggs to Marauders.
I've noticed that pure spec'd Jugg Tanks are becoming a rare quality too. However, I remain true to my Immortal spec'd tank. Unlike others, I use 36/3(Single Saber Mastery)/2(Decimate) for my Jugg. I may not do a lot of damage compared to those who have gone the hybrid route; however, I do have staying power, can stand up too and tie up 3 or 4 opponents while my team mates burn them down or take the objective. I defend my healer to my last breath and a node.
I enjoy playing him and very satisfied with how I have geared (all in augmented (fortitude) WH). I know there will be those who condemn me for speccing out the way I have, but the tree in its entirety gives my Jugg the ability to stand in the middle of a hot warzone taking a pounding, soaking up damage whereas my team mates are not. Thus is the life of a true tank.
