So in my opinion d3 if it’s even planned or not needs a brand new engine. Halos engine wasn’t meant for dungeon crawling or the many different foes we face to become legend or at least slightly heroic since my level 576 still gets taken down in 2 or 3 melees on a 280 heroic story mish ... sigh 😪 Heck! We don’t even have vehicle combat any more compared to halo’s vehicle splendor.
