Not me... I discovered Capella. Concentration is secondary to taste, and Capella, thus far, has the best flavor that I've tried.
Concentration doesn't even really matter IMHO. Unless I'm truly missing something, you just getting a lower amount of carrier liquid + about the same amount flavor molecules. "Whatever" in my book on that point.
So, regardless of that: if you haven't yet tried the China super-concentrated ones (VapingZone or EcigExpress), you really could be missing out on your new favorite flavor. There are some truly outstanding flavors to be had in the lineup, and they are very easy to use. There's now also a pretty well built out library of information on them. Hangseng's Essense line is on my radar as well, but I haven't had one of those just yet.

By the way... Wizard Labs flavors are actually made by TFA, and repackaged in 8ml vials.
Yep - the vast majority are TFA (including this one). There are also at least a handful of LorAnn and Seedman flavors there too though, so check the product descriptions.
Finally, in re OP: nicotine technically may also be a suspect. This wouldn't necessarily be a flavor disappearing act though, more of the nic flavor bleeding through.
But like salem said, isn't it funny how taste and smell can fade after continued exposure? I wonder how much of that is in the brain...it's certainly a different effect than how a background noise can "disappear" from your consciousness. That's something you can always decide to "get back" and hear again (provided of course, you could hear it to begin with). It seems we can't "decide" to taste a flavor or smell something again. Instead, it requires getting away from it for a time first.
