Why give the ability to lockout classes for Raids?

No, not potential. BLM are the highest parsing DPSers. FF Logs provides statistical proof of this.

I think you’re misunderstanding a little bit. Yes, BLM are the highest DPS if you look at “All Bosses” in most percentiles on FFLogs (selecting individual fights will yield you different results, because “All Bosses” is a combination off all 4 boss fights in Sigmascape). However, what Illyrian is saying is that you have to be good at the job in order to reach those high numbers. They’re talking about personal potential.

We're not talking about individual players. We're talking about the job itself. The job, based on the data from all five fights in Sigmascape savage, is the top DPSer. End.

Are you looking at individual fights, or just “All Bosses”? Because individual fights will give you different results.

If you look at Chadarnook (since he’s the striking dummy for parse runs this tier), for 50th to Max percentile, BLM ranks as follows:
50th: 3rd
75th: 3rd
80th: 3rd
90th: 1st
95th: 1st
99th: 2nd
Max: 2nd

99th percentile, all bosses Sigmascape savage. BLM is #1.

Next.

Phantom Train (99th): 2nd, under SMN (though SMN can pad on the adds in this fight easily)
Chadarnook (99th): 2nd, under MNK
Guardian (99th): 1st
Kefka (99th): 1st
God Kefka (99th): 1st

That being said, however, you’re looking at almost the absolute top, with the absolute best players. 99th percentile means they are better than 99% of players that upload to FFLogs. You cannot apply the play of 99th percentile to the average player, which goes back to what others are saying when they say BLMs have the potential (read that as personal potential, not job potential) to be the Top DPS. But not every BLM can live up to 99th percentile standards.
