SMNs can easily solo plenty of NMs, there is nothing weak about a well equipped SMN. Same with PUP and BST. If you take those jobs seriously they are amazing. Most people think they are jokes so they play them like jokes, but I have friends that play all of those jobs and they are capable of soloing all sorts of content that generally requires multiple people.
Well that really doesn't make any sense since SCH doesn't get Temper, Enspell 2s, Haste, or Gain spells. The only one you can sub is Haste. I don't want to Accession any of them either. I just want Composure to allow me to distribute the buffs that I get in a more convenient method. You can still enjoy that you can cast your buffs outside of your party, while I can be put in a specific party to support a specific group of people.
And honestly if you want to start jacking spells from RDM, we would be happy to take stuff from you. Don't think we have any interest in sharing anything that is actually unique to RDM at this point, since you already get almost every benefit a caster can get from /RDM. If you want Enspells, Temper, Gain Spells, or Refresh 2, we expect your unique toys in return.
