Summoner doesn't do the damage the parser is showing. There is an ability that is being listed as doing far more damage than it could possibly be doing. I forget what it is but cutting it out puts Summoner at just below the parses of Bards and BLM (this is adding the pet and summoner together). It is generally agreed within my FC that if Summoner is doing more damage than anybody else it is only by a little bit, not the leaps and bounds the parse is showing.
