By this I mean fights like Dark Animus in ToT or a fight like Durumu where it was a visual test on the maze, which is quite rare in raid bosses. Also included would be vehicle fights like Malygos or Flame Leviathan.
Do you enjoy or dislike these kinds of unusual challenges? And why?
I find them to be a huge pain to learn or explain, but often, once you've "figured out" the "trick," they can be quite fun, or quite easy. Animus and Durumu and Ji-Kun, I feel are all examples of that from ToT, going by your definition.
However, it used to be that I hated those sorts of fights- Rhyolith, Malygos, Flame Leviathan... ugh.
