Optimal strat is still Pit 100+ whatever is the highest tier you can clear in 90-100 seconds average. I did 300 last season with two friends and we were able to grind 110-115 in 90 seconds took a long time but we just did 3-4 hours a night for a few weeks straight. It’s not that exciting but it is a nice feeling of relief once you finish. For anyone else though I recommend 270ish is a good place to stop, paragon is very much so complete at that point it’s just getting the +5 core stat nodes from 270 onward for most builds.
