45 second 15% Balance versus 75 second 10% Balance ... which is more effective?

So, you notice how the gap gets significantly less when B4B is involved? Now consider that B4B is not the only CD or oGCD skill being used and the gap should not only get closer, but even swap which buff is better. Also consider that not all jobs are created equal, and some will benefit more from enhanced, while others less.

I do agree that most of the time extended is better. I said as much before we even started debating. I just don't agree that it's better "under any circumstances".

The gap gets bigger once time dilation and/or celestial opposition isn't involved either. And this is only in case of dragoon where blood for blood is at 30% and available rather quickly. If we to consider raging strikes instead (bard, black mage, summomer, machinist), which has a 180s CD, the chances are much greater that this won't be up at all during the duration of either.

So even if the gap gets small with just blood for blood, enhanced doesn't necessarily get better. Especially if you cannot extend the duration of it if you used it for other purposes. With openers, perhaps, where everything including potions are thrown out. But in this case expanded may or may not do better if you were to include other factors like hypercharge, requiem and/or trick attack or other forms of party-wide damage increasers.

In the situation where everthng is available; multiple buffs, time dilation and celestial opposition. Yes, enhanced might outperform extended. But this is relative with a ton of ifs attached to it.
