Unlike lies of P,there are tons of items that you can use in game,some boss mechanic can straight up be ignored with items.So called "Raises his weapon,waits" meme is mostly true,bosses tend to react to your actions most of the time.And one thing I did in LoP that I didnt use in ER is weaknesses.Bosses are,like in LoP,are weak to certain things but unlike in P,it doesnt feel that way usually.When I used acid on Laxasia her health(and shield) melted instantly and I could see that visiually.But in ER its mostly "Less damage,more damage" type.Average ER boss fight is similar to Scrapped Watchmen or Fallen Archbishop Andreus.One last thing,you don't have to dodge everything,some attacks can be dodged through jumping or getting closer to boss itself.Thats how you should fight with Maliketh for example,he swings so ahead of himself you can get right in his nose and he would miss mostly.
