[Discussion] How do you define a fun boss fight?

I like a good combination of gimmicks, skill checks, and motion. I also love it when there are more than one way to complete the fight, yet it is still hard enough to have to do it over and over again until you get it right.

The easiest example is T2's rot vs enrage. I'm glad both strategies exist.
But also in T4, we had an unconventional team the other night and did really well using our own heads instead of doing things by the book. I love when that can be done.

However, the most fitting in the game would be 8 man dungeon designed specifically for armoury system. A dungeon where changing jobs inside is allowed, and every encounter requires different party composition. Of course having to complete it with same players from start to end. Example fights:
1. boss that deals 6k damage to 6 players with highest enmity every 20 seconds. Alternated with an attack that deals 6k damage to single target from 4 of highest enmity, marked 5 seconds before.
2. Flying enemy that cannot be hit with melee attacks.
3. Boss that reflects magic damage.
4. Boss whos attacks reduce maximum hp. Ignores stoneskin, succor and adloquium.
5. Fight against 3 enemies that does high damage to single target, and each does an attack that increases damage taken for 15 seconds, every 18 seconds.

Only enabling elemental weakness and resistances would greatly increase the possibilities.
