Weird this boss have zero elemental weakness. Would expect mage to finally have a boss but this is another melee/range..
Ele Weaknesses still play into the fight, particularly if you're doing less DPS than people in high-end setups and having more incentive to stay on top of obstacles or minions during the fight itself. Even if they had weaknesses, we'd still want people to be switching because that was the aim here, my understanding is that it felt a little incompatible with the content's intended aims, while it's somewhat believable that these particularly powerful Giants are proficient Magic users
