This article covers two of my pet peeves from 3e and 4e (I'm edition agnostic, all versions of D&D can grind my gears
and make me dance).
These two peeves are: 3e's
Dire-Hippo spikey nonsense and 4e's cringe worthy
Webvenom Meanspider silliness.
(althouth 3e did technically start it with late-era monster manuals and Ebberon dinos, 4e made it something... special... and not in a good way).
Both Dire-Hippos and Webvenom Meanspiders need to go the way of THACO and descending AC IMO. I'm pleased that there will be Spotted Lions, Sabre-Toothed Tigers, and Cave Bears. Oh My!
In the case of the dinos, I am all for flavourful names ... but the thing is that Wyatt's Ebberon/4e dino names are in no way flavourful (or at least, not flavoured like anything I'd put in my mouth). They should not have been presented as such in the wording of the survey questions because it loads the questions with a certain bias.
As an aside, the latin/scientific names
are also the common English names. The idea that D&D shouldn't use those names because there's no latin or science in the Magical Land of Zog is no more right or wrong than expecting the inhabitants of said Magical Land to use words like "Goblin" or "Coatl" or "Tarrasque" or "Samurai".
My preference, which was in no way allowed for in the survey, is for flavourful dino names without the portmanteau overload, plus the English/scientific names in parentheses.
Also, dinos should be included in the core MM because...
DINOSAURS!
(all IMO of course, YMMV)
