Three points:
A) Indeed you can say they did a poor job. You can say anything you want. Even that Earth is a disc holded by four elefants standing on a giant turtle.
B) Really funny that you marked on bold anything BUT the part in which they say that ears longness changes author by author so that there's no canon apart knowing that in the western world they are short, like Lego one, or LOTR movie, and in mangas they're long.
C) Be serious, Wikipedia is no source. As long as you link me something where I can go and change the definitions to suit my ideas, that won't make any sense to me. Wikipedia started as a good project, but sinked like the Titanic, 99% of the pages are non neutral or filled with wrong informations. I can tell, I was a wikipedian too, years ago, and I left because if a group of people, large in number, wants to overwrite real facts with their own version, they win but that doesn't mean that there's reality in their words.
However, I spent 15 years playing D&D and I will go on, and that's really funny of you that you tell me this HERE, a place where I can say that I spent 28 years after LEGOs and I will go on.
By the way, just a note. Since you were the only one complaining about the elf, two are the cases here. Either you are enlighted by some Elf God and you are the only one who really knows Elves around, or you should think to fly lower. My girlfriend accidentally saw the pic and said "They made a Lego-Legolas!" and I am really looking forward to get lots of it because it fits fantasy era actually more than dwarves or orcs.
Contradicts what I said?
Where?
And just to end it up:
Fan's interpretation of an elf, found in .1 secs on google image:
Since I use to play LARP since 12 years too, this is what elves look around by ever:

See the ears? Short ears, as we are used elves are.
If you think elves are this:

you are wrong way, and you show you are actually confusing actual fantasy with final fantasy...
Fantasy Elves as we meant them were created by JRR Tolkien, and they have short leaf-shaped ear and they are not all that graceful since they divide in various kinds. Already said that, but you probably missed it up..
