If you don’t watch any YT made by streamer, you will find that your minion build are stomping all content in Torment 2. Other difficulty mode is just aspirational and every players are struggling inside.
Every season also have a class which is broken, even Necro minion was broken in Ptr S4 if the streamer didnt report the uncap scaling of Golem Mastery. Sorc Fireball has double dipping bugs with Uniques. Sorc shatter is possible still double dipping with hundred billions damage. All these are less broken as they are old class which the dev has fixed many bugs in 1 year’s release.
You are feeling slog with any other class because the content is designed to make it slog and slow you down. With the intention to keep your eyes staring at the MTX shop longest possible. Just some class someone found broken builds and get away with the slog system, after they have invested hundred donkeys hours in dummy room.
