What if certain bosses had the oppositeof an enragetimer?

They tried that around 2.1 with the dungeons, it didn't go over too well. The dungeons were quickly nerfed.

The reason for all the dps checks is because FCoB was beaten in its first week. DPS checks are the easy way to prevent that, and cause much less of an uproar than the alternatives, such as daily/weekly lockout on attempts or tedious grinding for each attempt.

Not even close. The dungeons in 2.1 were obsolete with the average gear levels people had so people were massively over geared causing people to push the phases too fast and it made things harder than they should have been. If you're DPS sucked the fights were surprisingly easy, just long.
