I did 3 kind of run after I was accustomed to most of the dungeon's mechanics:
- First run was solo. It was fine.
- Second run went in with pug. It was slower.
- Third run went in with my group of friends (one of them was first timer). We were melting things noticeably faster vs my own solo & the run with pugs.
I choose to just solo my way through the rest of my uncleared routes after my friends had to go lol.
