For this list, I don’t base on teammates factors, just me. Because if my team is bad or don’t know the gate mech then every gate is equally difficult imo.
(Maybe except for Valtan g1 because the team can wei cheese it)
I don’t think it is hard, maybe the third one, but are indeed harder than vykas/valtan. My reasoning is that is more erratic an unpredictable, leaving some failures to the RNG, of course there are things you can compensate with experience but that RNG, bad timing or whatever you can call it is more common in kakul than the other raids, maybe vykas g2 has some of it but not that common for sure.
