I posted a thread about exactly this a while back and got a few cool recommendations out of it.

Tower of Frozen Shadow was fun but difficult. Keep Summon Corpse ready with coffins in the bank.

Nurga/Droga had some potential to them as well. You could probably camp an Earring of Essence.

Wyverns in CS are an option. Sometimes they're overcamped but at a good hour you'll have the beach to yourself plus you can farm Velious quest gems.

Dreadlands are king if you want constant safe pulls for fear kiting, but it's kinda boring.

Oggok Guards are still a great option for money and xp at that level. I did them until 47ish but I think they can be taken further.
(Grobb Guards are an option but they become significantly easier at 49)

Depending on your gear, you could do Ice Giants in Everfrost. I died a few times but several people were surprised that I was taking them out easy enough. I recommend just camping the one in the back to fear kite down the hall.

There's probably more but those are the first ones that came to mind. I spent a while in the 45-48 range so I tried to do as many different spots as possible so I wouldn't grow bored.
