They tend to make Ex dungeons so easy that it's almost impossible to wipe in them, I was healing and DPS'ing in Baelsar's Wall at i230 (min. ilevel) without issues.

Even if you shave 2 minutes off from each run, it's going to be 730 minutes "shaved" from daily Ex runs each year. That means you have over 12 hours free time to be spent doing something else.

And I'd say that two minutes out of timer is quite low DPS for healer - they can do quite high amount of damage.
