Adding my yes.
Considering this game has been the #1 most watched game on Twitch for a good while now, along with CS:GO, Dota2, Hearthstone and League of Legends, all of which subsequently already have a dedicated forum on d2jsp.
And considering how active the game is in general I think it would be a valuable addition to the forums. According to Steam's own stats it's currently the most active game on their platform.
