Paragon guys commented on some live-raid, that doing the actual PTR provides some grounds for creating tactics, but due to the odd testing times (in Finland those times are past-midnight, like from 02:30) as well as constant lag and bugs, it hardly works as a real raiding environment to practice with. What it all boils down to is being able to take your schedule and make time when a content patch hits, as well as continuing to deliver solid gameplay after gruesome amounts of wipes.
