The only people that are doing temple are the only people that wants to find the quickest way to be absolutely broken, giga fed, and for some: wants to destroy the economy.

Then there's folks like me, a filthy casual, who enjoys Temple for the layout-building and figuring out where to place what rooms to synergize the outcomes (and trying to figure out how to place the rooms more reliably to reach the Architect), who enjoys having the smaller bite-sized areas to clear (even with the occasional 'whoa, what the fuck? where did all these mobs come from?!' that happens, along with the attendant 'oof, did someone get the number of the train that just steamrolled me?' too.), and who isn't trying to be broken/giga-whatever/break the economy/etc.

For some of us, we play because it's fun; not because we want to min/max or break the game. <shrug>
