Question

Just got to the quest " shadow of Darkness" and was wondering how can I get better equipment from my character? I'm a lvl 34 acranist/ summoner. And why does my character banner still shows up as acranist instead of summoner?

Another question I have is , when is it a good time to start another job? Should I max out one then work on another or what ? I thought about being a weaver so I can craft my own equipment but idk. Kinda lost here

Thanks for the input
