Shaman soloing 58-60

[Weltmacht]

Hail and/or well met,

Looking for some advice, if any of ye would be so kind. Good ol' city of mist has started to green out, which is a shame. I really only ever have 30-60 minutes per session to play, which makes grouping an unrealistic option. I've been able to do 52-58 in about a level per week doing a few quick sessions a day which has been great, but I fear for my sanity at the prospect of grinding greens at 59 :O.

The only other option of which I'm aware is HS, but I would prefer to keep my OT faction if at all possible. Any/all (give or take) advice is greatly appreciated, so thank you all kindly in advance.
