User blog comment:Alartan/Swiftness or Mobility boots?/@comment-4843720-20150202011710/@comment-24590723-20150206142009

I get your point, but Sejuani works like support.

She can make things like worse version of Amumu, but I mostly initiate teamfight and then peel for carries. I rarely need to pick back-line targets. Both e and r are ranged, q is gap-closer, only w really need me to be nearby.

With perma cc from 40% cdr it's impossible to get away from her anyway.

I rush mobilities as optimal choice for early-to-mid pressure from ganks. Most of players buy boots much later. Then, later I have 40% cdr.

When I used to buy jungle item first I was chosing other boots frequently.
