I've been in your shoes, tppk sucks, and to add another rant, I am dissapointed this didnt get patched with the reset.
The ultimate antitppk build
WolfBarb , my about avg wolfbarb has just under 8K life. Throw on 40+% DR (stormshield,vendagoes) and overstacked res, their isnt any tppk attack in the game that can deal enough damage to kill you in one attempt.
Avenger pallies do real well against the elemental tppks, they dont have the life like the wolfbarbs though so windies and bone, GA still hurt. (Avengers use vengence which gets is syngerys from maxing the res aura's that in turn increase you passive res) Throw on GA plate and laugh at the attempts
I run lots of sorb when pub running
Tgods, 2 ravens , Rising son for 20, 40 and 55% sorb to each respective element.
Goodluck
