Someone please correct me if I am mistaken.
All parsers run a simulation for DoT damage, or just don't simulate it at all.

All classes use DoTs, but the more DoTs you use the more inaccurate the results will be. Over a long period of time, it is fairly accurate, but no fight really lasts for a long period of time. It also doesn't account for variables like clipping, CD usage, etc.
