There do exist some fights that actually feel like a struggle, so they can actually design fights like that. Unfortunately, it's mostly old fights or ultimate phases.
Nael phase in UCoB felt like you were actually fighting someone that wants you dead, Living Liquid in TEA as well, Nidhogg in DSR also felt like he wants to kill you, all very fun phases that incorporate environmental tells, boss tells, player markers and player debuffs.
Meanwhile, TOP does have quite a bit of debuff vomit, which would explain why it's had such mixed reviews.
