I have always wanted to see a mod that adds herds or groups of trolls/frost trolls. It would be neat to see groups of maybe 5-10 of them together in certain areas, especially around Winterhold going towards Dawnstar and also the other way going towards Windhelm. It would add a unique and challenging encounter ( since now there is a herd of them running at you ). In my previous playthroughs, I have always just console commanded them in, but it would be cool to see them modded in, then maybe they can "patrol" the wild areas of Winterhold, Dawnstar, and Windhelm.
