@Athena I think you beat the game right now and there. Giving out Top 1 Eternal Rogue build while maining a warrior? I have no words for it 
Thank you, I will definitely try this but now I need to farm crystals and items for this, which is gonna take me some time, but I hope not much, because I am using the Flash Farmer + Miss Fortune build which I want to share with others on this forum in the next days
As for the Momentum affix:
So according to this post I have [(100% + 0%) * (momentum set number) * 10%] bonus dmg, which is 30% bonus dmg for Arena, where momentum set number is 3.
See you in div 1 and once more time thank you
