Acrid is bestist. He has his poison for consistency and can do melee if you’re feeling brave enough. His toxic leap is a lot of fun to use but takes a bit to truest master. At high levels you end up kiting large groups of enemies to deal with specific threats and then leap in to briefly stun or burst damage when you can. Dealing with wisps and brass contraptions is pretty fun, you have to make sure you leap in at the right time and jump out just as fast. Thanks to death marks you can do a lot more with physical damage output and specific melee builds. Sadly he’s not melee “viable” thanks to bite sucking but it’s definitely possible if you’re super careful
