Spoiler alert - this is going to come off as kind of elitist
Highest DPS only matters if you actually play your job well - A poorly played monk is going to do low DPS no matter how "optimal" it may be as a DPS option.
Further more, the optimal is based to an extent on the content you are doing - I pull higher numbers on summoner in T13 than our black mage usually does because of double-DoTing and other stuff, but I get spanked in T10.
Pick a Job or Jobs that you enjoy playing and don't worry about being optimal - Unless you are playing with a team of server-first clear seekers for high end raiding, the meta doesn't apply to you. I've done WoD runs with mnks pulling 101 dps (How I don't know but they pulled it off) and people coming in on Arcanist without a pet summoned (52 dps...) and guess what? we still cleared, got drops, and despite my complete and utter confusion, everyone else seemed to have fun.
All jobs with gear can meet the minimum DPS requirements for final coil at the moment. Again - it only matters if you're trying to bum-rush the content week 1, and if you are at the moment only level 32, i doubt you will be pouring hundreds of millions of gil into over melding crafted gear to be the first on your server to clear alexander any time in the immediate future.
Just enjoy the game
