Can I have 0.1 Hexblast back

Hexblast in 0.1 synergized with Blasphemy, allowing you to detonate the aura version of your curse repeatedly. I feel like currently we have not gotten a good replacement for this fantasy/playstyle. It was incredibly fun and a large part of how I got hooked into Path of Exile. Hoping it makes a return eventually. I feel as though the current state of Hexblast is F tier/unusable. Waiting on the duration of a curse to reach half... not being able to synergize with blasphemy... just feels lame. Does anyone else miss this interaction?

Side note: I saw a build creator in 0.3 purposely make Hexblast work really well for bossing, and it was very strong.. however it looked like C&B torture.
