Well i don't know about all the knight class combos that are out there, but K/S is supposed to be one of the best tank combos there are correct? But as an endgame W/WD when I get fully buffed for a boss fight with over 130k pa and 25k pdamage after charge buff, and wind howl, and with the -15% aggro reduction from Battle Creed buff, I still pull aggro from a k/s with 2 Hatred IX's.
K/S is supposed to be the best tank combo IF you use Knight as primary. But just about any other class combo built to tank, without Knight as primary, will take aggro away from anyone with Knight as primary, as you have just shown, even though you were not trying to tank, and thats the same thing that kept happening to me, which is why i switched to tanking as Warrior primary.
Most of it is probably on me because im only using a Recon VIII but that's because I cant bare the thought of upgrading cost to a IX.
I think this gets back to the main topic at hand. Can the nerfing of Knights be traced directly to the need for profits. Unless you have loads of cash to dump into the item shop for Hatred X's and thousands of charges to T12 and +16 your pathetic little Knight wep, it's almost impossible to do your job as a KNIGHT PRIMARY tank, unless everyone else in your group dumps loads of cash into the item shop for Rocon X's. So the way us poor players who still buy diamonds, but few and far between, remedy the situation is change primary class to do a better more affective job at tanking.
