House of wolves, its not even close. Intoduced trials, treasure keys hunting wolves on patrol, poe 28, 32, 34 and 35 (skolas), re roll weapons, iron banner had best weapons etc. In addition, best shotguns, handcannons, snipers and hopscotch pilgram etc. It was a time for tons of weapons to farm. So many weapons to be excited for, just not happening in the current game. Taken king was the best major release.
