I personally believe that there will be alot more baal runs now since there will be more people playing. At a certain point, most people will be looking to do baal runs, so there will always be games. But it will be harder, no doubt.
The first week or so into the ladder pre-D2R, people farm baal without bots aswell. Takes abit of time for the bots to get their gear in order. But after that point, most runs are run by bots. Hope to god that won’t happen in D2R.
You could easily make a baalrun game yourself and people will quickly join, but people are lazy, so if there isn’t any sorc to consistently teleport to the throne room, people will leave. Easyest way to do hell baalruns is to roll a sorc yourself, learn the map tiles, and teleport to the throneroom, hoping you don’t teleport straight into a pack of dolls or get instasapped by souls.
