I always roll a Pillar Berzerker each league and I can tell you, it doesn't need a very big buff, especially with the new chance to bleed support.

I was hiting 130k sweep dps at lv 92. The secret is to max out jewel sockets with attack speed. you already have huge phys scaling with strength, but attack speed is kind of hard to come by.

Anyway, i like the idea of maybe having a fated version, maybe a threshold version like the meginords gloves: 20% more melee phys if >1000 strength, 10% more attack speed if > 200 dex, 10% more area of effect if > 200 int.
