I don't think SE consider D4 RDM in the mechanics in this patch

[luca20]

As someone who progged most of M7S as RDM in the R2/D4 spot and changed to PCT as soon as I could, I feel the problem is not RDM or fight design, the problem is the job balancing team hard on on melees. If RDM was competitive with a melee for damage then this wouldnt be an issue because you could easily join parties as the flex dps and take the melee spot. This is not only theorical but something you see often in ultis. I progged most of UCoB as fake melee RDM and have seen it as well in DSR and FRU when it was current. But with how much better melees are than any job not called BLM makes it so that there's no flex dps spot, it's locked to a melee.
