Just started adventure mode; Nephalim Rifts are amazing. Killed enough to summon the Rift guardian in one of them, and it led me through a couple of packs of Elites that I had not yet killed. I died a whole bunch ( that happens when you fight a Rift Guardian at the same time as four Enchanted Waller Freezing Imprisoning Fast Extra Health Fire Link etc. Elite packs ), but eventually got them all.
Funny how the game's actual bosses don't really do much of anything while some of these packs can absolutely murder you.
I played pretty much exclusively Frenzy/Whirlwind Barbarian up till 70, I didn't really think the other skills in the respective slots were worth that much. Then I found The 300th Spear and damn son, Weapon Throw ( Ricochet ) + Ancient Spear ( Boulder Toss ) is insane.
