All the bosses have some kind of DPS-race factor to it, but that's not all that they are; even the simple switch back and forth thing of the twins already is something different.
Like, the monolith fight is very fun, probably my favorite; having to patrol the area around the NPCs, kite giants, use the buffs, it's a lot of small things to do there; but then you literally attack a stone that is standing still at the end. Haha.
I hope there is more creativity in the next raid, but this one already is a good indication that this is something that, today at least, you can only get in this game; it's long 10-person boss fights without healers or tanks, but also it isn't everyone doing the same kind of thing because the characters themselves are so unique; you have to work as a team, but you aren't babysitting anyone or expecting other people to protect/heal you. You do your thing, but you do it in the context of an unit or stuff doesn't work.
Again, I hope they can get this unique set of building blocks they have and do something crazy with the next raid; this one feels more like training, to be honest, gear checks / DPS checks / "can-you-work-as-a-team-in-a-very-basic-way?" checks
