New player reached lvl 60: what ways to improve gear solo?

[JazVM]

Hello guys,

I just reached level 60 on Treebeard and it was great fun! However, I am complety lost now. Grouping is not an option for me due to family responsibilites and time constraints so I can only play solo. Currently I don't see any way of improving my gear without doing group content. Is that correct?

Is there any way (quests) that award motes of enchantment or medaillons of moria for solo players?

Is it possible to solo group content (my class is warden) to get currency? If so, what instances and what kind of build do I have to get there?

Is there any use for Embers of enchantment right now? Can I somehow exchange embers for motes?

Thank you for your responses!
