Is this truly wrong?

I enjoy SMN a lot, yes, and I pretty much have my rotation/priorities down as opposed to say, DRG or SAM or RDM.

There are a couple of things you're forgetting. Gear makes a BIG if not HUGE difference.
When you have ilv 371, top food, top pots, get buffed up the wazoo, perfect party composition... yea it ain't that hard to make one perfect parse.
Does it mean it's reality? Hell no. Reality is, people make mistakes, people don't always have perfect stats, etc.
Never look at FFlogs assuming its reality. The other day i had a "top percentile raider" only interested in top DPS... ohhh boy did he let it be known he was a top percentile raider.
The guy was dead on the floor due to mechanics more than the first-timers.

So focused on damage, DAMAGE, DAMAGE!!!!! that he forgot the massive AOE going straight to his face...

If you're certain that you improved rotationally? have you considered that it might be the gear you're wearing? I'm no expert summoner, but I am someone whom knows Bard through-and-through.
If I drop an item with crit on it for something with skillspeed or det? I can see my damage take a nosedive. Might want to look into that direction

Most importantly; numbers are not an accurate representation of skill, I rather have someone with lower damage whom rarely fails mechanics than someone whom is top damage but failing repeatedly.
In the end it's more important to get the job done and have fun while doing so.
