Most World bosses work quite well in the current status, but it's very annoying and immersion breaking, that some Bosses like Kzarka, Kutum, Garmoth can just stand there unleash an attack at you and you can only evade. Isn't moments like that where you consider if you can take the hit and survive and not be forced to just evade the attack?

Although Kzarka and Garmoth i-frames very immersion breaking, Kutum is the most annoying of the ones I mentioned, because it has a slow charging AoE attack and it also dives into the ground a lot. For example today's (3.11.2022 UTC 8.00) second Kutum spawn on EU Baleanos 6 server kept diving underground non stop. We are either forced changed servers in hopes of finding a Kutum that doesn't i-frame all the time with diving or AoE attacks, or just hope that it will eventually stop so we can actually do some damage to it. Or just afk, because trying to beat World Boss that can't be hit, is definitely not fun and just a waste of time.

You don't know pain until you do a dozen awakened griffon scrolls.
