SE wouldn't know what balance was if it bit them in the ass. They throw the word around because its a trendy word in MMO's it provides the guise of actually working on shit. Case in point.
SMN's elementals now cost less MP to keep out, but still do relatively anything of use other than Elemental Siphon, which defeats the purpose of reducing MP costs since you use it for a brief JA and that is it.
That is SE balance for you, instead of balancing SMN's to actually be useful buffers or DD's via Ward/Blood pact timer reductions or charges, they instead target something that has absolutely zero effect on making SMN any better or worse.
Fluff is fluff is fluff.
Ironcially RDM has had its own experience in this. At the 75 cap SE gave us an awesome ability called composure, that extended the duration of enhancing spells, but only on ourselves. Now we can extend that bonus to others, but our spell library has been reduced (in a sense) considering the only buffs we have to cast are Refresh II and lolPhalanx II, Everything else is now available for use by other jobs via sub jobs.
BRD can cap haste by itself for a whole party. (RDM can only give 15%) while /RDM
BRD can give 10MP/tick refresh for a whole party (RDM can only give 6) while /RDM
BRD can then give its other buffs as well (up to 4 AoE buffs at a time)
BALANCE!!!!!.
