It also has a gap closer and a gap opener, which are much more intuitive to use compared to BLMs teleportation skills (which need targets either way, and therefore cannot be used most of the time, if your ley-lines aren't up or if you play solo).
There's also the issue of support, and resource management. BLM is never g oing to run out of TP. If you do, you're playing it wrong. That's a very nice thing to have and makes us very good mana batteries. RDM in comparison can go OOM if they're not careful, especially if they use their support - something BLM doesn't have outside of the role skills. RDMs have Vercure, and they have VerRaise.
But yeah, they play the same because they're both casters, don't they?
