Pretty self-explanatory. Feral Water Buffalo are pretty common in Australia, and the landscapes on Emerald Coast are very similar to the areas of Australia where Water Buffalo live. Furthermore, we only have one map with Water Buffalo currently, and I'm sure that most of the community would like to have another map to hunt this species. The Water Buffalo was also the flagship species of Piccabeen Bay in theHunter Classic, a map that was basically Classic's version of Emerald Coast. The Water Buffalo is the only species from Piccabeen Bay that isn't on Emerald Coast, and I think it might be the most obvious and glaring omission from any map we've ever seen in COTW.
I know we already have so many species on the map, but Water Buffalo wouldn't even have to be super common on Emerald Coast, just add a small population of them and spread them out across the map (excluding some areas like the outback and some other areas of the map which wouldn't really be ideal habitat for them).
I just can't understand how EW decided to include Red Deer on yet another map (there's five maps with them now) and then completely forgot about the Water Buffalo, which is currently only on two maps. Let's show this old, often-forgotten species some love.
