Has anyone stopped and thought that maybe Bioware did this on purpose they allow u too choose 2 different classes either Jugg or Mara essentially Maras are dps Juggs are tanks and inside those 2 options they allow u too spec into 3 different trees just Like WOW but instead of limiting you too 1 single tree they open it up too allow u too spec into multiple trees like RIFT and tank how u see fit if U want Mid more then roll immortal u want less mid more dps then go vengence either way are viable speccs for tanking depending on ur play style so why argue over which one is better if ur good at what spec u like then fine.
As for the more threat where as in some instances more threat would be nice having it stack better with skills its fine the way it is DPS and healers should learn too play their classes first and use their skills too help u out with threat but if ur CCing adds and using ur abilities coupled with Dps and healers dropping their abilities threat is not a problem. Single or AOE best bet on single is if u find ur losing aggro save ur taunts for when they turn and roll ur taunts as they come off CD if u think u might have too move out of something and stop dpsing and could lose threat all these things help in the long run.
Now if they can only fix the boss glitches we'd all be fine!
