For learning Flash's range, I found it useful to practice it solo on some easy landscape mobs.

Of course, Flash doesn't matter to the solo fight itself, as any mob you're engaged with will be focused on you simply by the fact that there's nobody else for them to focus on. But on the landscape there are mobs that don't aggro simply by being too close, and will only fight if you engage them first. That makes them useful for learning just where Flash's range really extends. Get near some of these non-aggroing mobs and try a Flash. If you're within range, they'll react and start to fight you. If you're not in range, they'll continue to ignore you.

Try this multiple times at varying distances until you get a feel for just how close you need to be to get their reaction. Then the next time you're in a dungeon where Flash actually matters, you'll know how close you need to be to those mobs in order to use Flash effectively.
