Why do you say everyything past tense? Its a 10 year old MMO. The first one out on PS2, and was PS2 only. BUT, its still alive. Servers are still active. But, yeah as far as end game stuff, its probably one of the most balanced MMOs I have ever played.
In my opinion, that because of the "class balancing" process they took. EQOA put a dev in charge of every class. Gave us the name of the devs and there respective class. The dev posted daily on the specific class thread. Player feed back and dev communication was literally a multi-daily process. It lasted for months. Ahh how I remember the PMs with Deamaas about issues with the bard charm in that game.
In my pinion, what allowed them to balance so well came down to several issues. Most important, was that they decided to spend 3-4 month focused on class balancing. Its the decision to sit down and do it that got it done. They gave full disclosure. We had access to all the spell information. When they adjusted "Anthem on Conquest" they released a good deatail, about it.

Purchase of Anthemic Crecendo 5 increases the stamina mod to 20% and makes it an AoE

Thus telling you all you needed to know about the ability, and allowing you to test its over all feel and effect and debate it on the forums, with a Dev active and part of the debate.
All and al, I have to agree, that FFXIV has definently got one of the more serious balancing issues of MMOs out there at the moment.
