Least Played Class after New Update?

Due to the critical damage nerf, I thought Aran's popularity will decrease significantly, even snow charge is increased from 110% to 145%,
Aran's post big bang DPM is scarcely comparable to that of some massively buffed class (i.e, Corsair, MM).

Aran used to be 2nd or 3rd highest DPM class (below corsair but pretty close), but after the big bang patch, I think Aran's DPM will merely be ranking 8th or 9th....

Do you mean "even though snow charge was increased", or that it decreased? I'm not sure how a buff to a skill makes them less popular.
