Is there any reason to play BLM over RDM now days?

I'm just curious, because it looks like on FF logs, there are absolutely no BLM, and all the slots RDM took. RDM does the same amount of damage as BLM, but also offers utility, heals, rezes, and is super mobile. Is there any reason to actually level a BLM anymore? Or did everyone hop over to RDM?
