I was recently playing on SRP again and it made me remember back when the Pronghorns were added to the game not long after SRP first came out. Their drink time was in the daytime and you could hunt them with any Class 4-8 rifle. They were the perfect species to hunt if you were new to the game and wanted to grind XP or even just to hunt something for fun. They were easy to hunt, fun to hunt, and had me coming back to SRP over and over again for some fun Pronghorn hunting.
Now, they're a Class 3 species, which makes very little sense from a realism standpoint because they're commonly hunted with calibers like the 7mm and .308 in real life. The best weapons for hunting them in the game now are weaker weapons like the .243, or the .44 magnum rifle that has a shorter effective range. This makes them a chore to hunt for. Combine this with the fact that they now basically only drink at night, and now this beautiful and well-designed animal is really not fun to hunt at all, unless you get lucky enough to come across some while they're feeding.
Make them Class 4 again, and make them drink during the daytime (preferably from 12:00-16:00 like the Bighorn Sheep, since the two species are found in different parts of the map so there won't be too much overlap). If those two changes happen, they will once again be one of the most fun animals to hunt in the entire game.
