There actually is strategy in this. If you are running the dungeon as a sub-R50 class, then your party is probably just doing the dungeon for SP, and therefore killing all the mobs.
However, if you are in a party of all R50s, there really is no point to killing stuff for SP, and instead the strategy becomes a race against time. It is actually fairly hard to trigger all the circles, despawn all the mobs, and run to the bosses without suffering any casualties. It takes a lot of coordination and planning.
I would imagine that in play-testing they found that forcing players to kill everything got a bit tiring after the 20th consecutive time, so instead they turned it into just an option.
Remember now, what Yoshida said about "multiple ways to complete a dungeon".
There are rewards for killing everything, if you choose to do so.
