Pliney is a fantastic DIPA. But in the end it's still just a beer. And sure there are other equally good beers out there but then again I would say they aren't all that common either.
After it slows done you can increase the temp slowly to help the yeast fully attenuate. I like to bump mine up about a degree a day after the first day or two until I reach a set point, usually 68/69 for me, depending on the beer of course.
Your beer will ferment higher than the ambient temperature, so it would likely create cleaner better tasting beer. However your need for it may be less pressing than people who live in warmer climes.
