Blends are cool to when you need to create intermediate objects or colors, but these sucks when you need to create a uniform distribution — Ai stupidly uses’ the spine’s curvature to control both the spine’s curvature AND the distribution (requested to get improved here: http://illustrator.uservoice.com/forums/333657/suggestions/32403880)

But now we have Objects on Path, which can’t provide any other distribution except uniform one (yet, we hope).
But, as usual, two similar functions remain completely separated and non-ingedrated (we saw this before with Repeat Grid and pattern, and there is a request to allow conversion of one into another here: http://illustrator.uservoice.com/forums/333657/suggestions/45233863 — along with 'why can’t we add these as swatches, here: https://illustrator.uservoice.com/forums/333657/suggestions/41686228)

So it’s a similar one — allow to convert a live blend directly into Objects on Path. This would allow to solve the uniformity / acceleration for blends first, but then it’s just a question of cutting a corner between these two VERY similar tools.
