bruh just download it to your single player and have a blast, player 1 this shred everything like its nothing. at player 8 its still shred them like before nerf until boss battle. at sheet you see 4.3k eruption damage but after you factor in -54% magic resist from gear(can go up to -70 to -75% if you want to sacrifice + skill) its actually doing 6.5 to 7.5k magic aoe per echo. current patch physical echo is trash, only thing it has over magic is leech. you aren't killing crap until curse is triggered, and only way to get it is binding some multi shot harpy on live which blizzard will fix down the road.
Nah, physical is very viable. The harpie thing is just from the fairy microbioboi-- it is definitely not the best demon or physical build. My physical only echo can do p8 heralds, ubers, colossal ancients, etc without potions
