Honestly speaking here. It's fun to play through, get through the storyline and seasonal. Then when you're done with 8/8, be done. Shouldn't take but a week or two. If you need a boost, message me and I'll help. Any build out there can clear through T3. Farming chaos stuff isn't worth it. 200+ paragon and a meta build can easily clear T4.
