Basically, Arcane will be the same as Fire.
Old "spec niches" as we have come to know them over the years are dead in Legion, or at least that's their intent. And with the team actively trying to achieve equality instead of accepting that Fire is for AoE, Arcane for ST and Frost the overall good one those concepts are destined to die out and disappear eventually.
Of course one thing is having the intention of doing something and another is accomplishing it... but intention is what counts. They changed their mindset for Legion, and this will eventually impact how specs are perceived.
