I have recently played this alternative version of the The Scourge of Lordaeron campaign and it is simple amazing, so i’m recommeding it. It bring’s an extended vision of the original campaign, with a few extra missions, more heroes, more lore, more challenge, talent system for the heroes, expanded and modified original maps with the possibility of combining items to create better items of quality, secrets, an upgrade system between missions (like starcraft 2 use for example) to upgrade units, resources, structures and others. And also this mod have a room to replayability after you finish it for the first time, which is amazing.
Credits to Nituizi handagou, i’m just sharing the mod, available at the hiveworkshop.
