Never said that myself, but I get what you're saying.
Wakfu has great art, fun characters, some risqué humor and hips. People are constantly overhyping shows they love: if you take my previous sentence, put it in a shaker, mix all of that, you get "TEH BEST SHOW EVAH you guys have to watch it plus it comes from france, those lewd frogs".
In my opinion, Wakfu has one advantage. Since it's from Ankama, there's always cross-media involved. You liked that character? An OVA is dedicated to him. This one, maybe? Take a look at those comics. What were they talking about, back then? See, in the Dofus MMO...
Remember that between S2 and S3, we had Dofus: Kerub's Bazaar, 3 Wakfu OVAs and a Dofus movie.
