Fractal
Low level fractals encourage the use of high-burst builds (as bosses can be defeated before mechanics have a chance to fully play out), but higher level fractals can use both high-burst or high-sustain DPS builds. Raid builds are also easily usable for in fractals, but due to the stat bonuses gained from fractal potions some builds are able to make adjustments to their gear to optimize their damage.
