MSK Horns

So, I had a very disappointing run at the storm king yesterday. I played several matches and couldn't quite help with breaking the horns. I managed to assist with critting the crystals and help defeat the Mythic Boss. However, the horns are definitely my weakness. I have perked my Storm King Fury to include Critical Damage, Critical Rating, Attack Speed, Damage to Mist Monsters and Bosses, and a Physical element. I am running a Lynx loadout with Guardian Bull, Tank Penny, Rex Jonesy, Prehistoric Izzy and Demolitionist Penny. I almost have every hero in my loadout maxed to 60 as well as my Storm King Fury. I am also using (2) hover turrets when I get to the horns. It just seems my swings at the horns are not doing any damage. Although, I have a 53 % chance to do over 200 % damage. I was also curious is there is a proper way to attack as it seems once the players are together on the horns only 1 or 2 do actual damage. I appreciate any insight, suggestions, and or comments. Thanks all. I appreciate the community and sorry if you were in one of my teams yesterday. I'm trying to get better.
