There kinda were instant-death mechanics and puzzles to an extent though. ADL could instant wipe alliances if he spammed tera-slash, and there was some RNG involved to killing the right clone. Still, not knowing how he would respond made the fight a lot more intensive and exciting.

Puzzles came in the form of not being told how to kill the boss, and having to study the mob's hidden effects. Nyzul Isle was a greater example of puzzle/maze content that got the player problem-solving for each floor. A battle type I hope comes back for FFXIV.
