Boss fights are notoriously hard for solo people at the moment. So your sentiment is not unique. I stick to exploring and looking for blue or higher things to kill.
Everyone I've asked about it who was past lvl 20 or so said that soloing becomes roughly a gazillion times easier around lvl 20. You can start killing bosses quick enough solo to make a difference. I think Wollay needs to work on making the early levels more interesting and slightly easier.
My water mage is lvl 12 and I'm just starting to feel like I can actually make it though a tough fight. Still can't complete many quests due to the bosses being way to powerful for the level.
It's still just an alpha and I hope he addresses some of these issues.
