IF it was such terrible design, how was it SE's most successful game ever? It didn't lose subs for many many years into its lifespan, it has outlasted many games that subscribe to the WoW model (I'm not calling them WoW clones just to head off any arguments). With a glamour system there wouldn't be any more wasted art assets than in thsi game, certainly.
Actually, I found self-skillchaining gravitation (I think it was, it's been a while) into an MP drainkiss doubled my MP intake and allowed me to go between fights without resting on my BLU/THF.
Also, on my first job to 75, one of my most fun memories was closing Darkness Skillchains on Magmatic Erucas with Cross Reaper from the MNK's WS (Howling fist, I think...) for our BLM to Ancient Magic (yes we actually MB'd AM, lol we were noobs) MB.
When the game design changed to favour other styles of play (Merit-pt pulling Colibri and Puks), then favoured compositions and play styles did indeed change. Anyone who said LolDRG on Puks or Colibri was an idiot.
Yes, at that point Thief was given the level 60 ability (forgotten its name) that hugely increased TA damage and made it viable to use seperately to SA. They also got two additional hate transfer abilities also.

If you weren't singing these songs regularly you were doing it wrong. The only songs I think I never sang were the Mambos that increased evasion. Even a couple of the Carols were useful in Temenos. On Carby it was nearly mandatory.
If they all could, it wouldn't be unique, would it? Which is kind of what this thread is all about.
I think they're better than you're giving them credit for.
But then, I think my experience of XI may have been different than yours. I joined just after ToAU (xbox release) and left shortly after Abyssea.
