It was one of those examples of the game being made different just for the sake of being different. I suppose it's possible that as stats, etc get reworked, perhaps they'll consider this being changed as well.
All they did was separate the basic "elemental cycle" into two separate cycles. I believe the same was done for FFXII?
The FFXIV eLeMeN website has all the elemental weaknesses for each mob family up if you can read through some Japanese:

Thing to keep in mind about this is that theres more to it than just weak/not weak. I can personally confirm that elementals (at the very least) also have a slightly higher resistance to Astral/Umbral elements depending on what element they are. Water elementals for example, are weak to Lightning and strong versus Water.. but are also slightly stronger versus Ice/Earth than they are versus Fire/Wind.
And I did the bulk of my testing back in like October/November after first hitting 50 before fully realizing how far the game would sink, and haven't retested since seeing that we're all expecting/hoping for major overhauls in the stat departments. So apologies if this changed, but I don't think it has.
I'd really love to see some testing on this too, but I also agree that stuff is going to change so quickly it's probably best to wait a bit.
