My dots consistently do over 20% more damage than what they parse for. Parsers are only able to tracks when and what dots are up (except for shadowflare), but are unable to track the damage they do. A SMN in ilvl 60 gear will show the same damage from dots as one in ilvl 90. Parsers are also incapable of knowing when dots crit, which is substantial.

If you think you got a SMN beat just because your parser said so, think again. Geared SMN do quite a bit more than what is shown.
