Rathbreaker Balance Concern

Hi all,

I am a very new player to POE and have decided to play a witch for my first character. One encounter I found during the Rathbreaker fight was that it was incredibly difficult due to the fact that the raining spears were constantly killing my own minions. I have heard from otherr witches as well on the POE subreddit that they had a similar situation. I might just not have good enough skill, but, once again, the fight has felt harder than any other fight in the game due to the fact that it is almost played minion-less.
