I wanted to share my league start with you all, Boneshatter Shrine abuse berserker. It turned out much better than I anticipated and I have cleared all content besides the feared.

Pros:

• Fast Mapper (can use Inspired learning to go even faster)
• 12m Boss DPS
• Stun lock and 30% chill on bosses
• Berserk up time ~60% (20% more Attack Speed, Damage, Move speed, Less Damage Taken) (26% with enchant)
• 6 Endurance charges
• 23 Fortification on hit
• 20k Armor in hideout
• 79% all res
• 9 warcry charges with 15% life recovered
• Tidebreaker

Cons:

• Strike skill (will get you killed in juiced maps if you click the ground)
• 10 button build (+ in my eyes)
• You can nuke yourself on bosses if attack past 16 trauma stacks
• Boss dps comes from ryslatha's coil and Forbidden Flame/Flesh Tukohama War's Herald (Ancestor Totem buff effect)
• ~ 10ex investment for bossing potential
• need reflect ring/watchers eye for Atziri (110% reduced required)
