How long should a boss take to go down to still be enjoyable? While regular raid guilds kill bosses quicker every week LFR remains at very high (and boring) kill times - LFR decreases in killing times after raiders don't queue anymore. Some mythic guilds just remain stable because they only have to put effort into progress and have the rest of the tier "free-time". Average guilds plan like 3-4 nights per week as normal progression and farming path which includes high time investments into bosses you might have already killed.
So to get all players into this poll: How long should a boss last till his mechanics and your patients runs of?
