Changing the elements of the monsters from what they normally are seems really odd. You'd expect oh hey its Byalan, lets all go get our wind stuff together and murder some fish. Nope. Same with the Races. I'm not really sure what kind of restriction you're under to create/modify monsters every week. But if you want to reuse old models at least make their race/size/element reflect what the original model is.
So is the weird difference in the HP of the Phen/Penos compared to everything else.
We discovered the size is off so next server restart that will be fixed.
