Advice on places to level mainly solo

[Shibby]

Hey all, just finally dinged 46 on my druid! I also just purchased a lumi staff. I'm curious where I should head to level now? I've been at spectres the last 6 levels or so, and am looking for a good place to use the staff to have no downtime. Also was curious what level the staff is good until. Thank you for your help and suggestions!
