AoE Ele build?
You are actually in huge luck. The meta staff ele build fits all of your criteria extremely well. Just about every attack is an aoe of some kind, the build performs decently on its own (although dagger/focus works better solo), the build is ridiculously useful in groups (even without ice bow), and for the most part you will be camping fire attunement and only using other attunements very briefly or for specific situations.
A great guide to the build can be found here:

Wow that’s great, glad I asked on here for once, usually I just try my own builds and they normally turn out pretty good, I’ll see how this one works in a few.
