hecarim unviable in preseason?

With the new Hecarim skin on pbe that looks amazing as hell, I thought i'd pick up this champ after his nerf out of top lane all the time from worlds. But i have been finding that with the new preseason he is, for a better word... shit.... As Hecarim was and always has been a bruiser that scales with items and is not innately tanky. Second by the fact that after the juggernaut update, just pushes him out even more. but what weirds me out about it, is how he is a feast and famine champ it appears. As in my last game vs a garen top, i knew i was boned and was going to have to farm hardcore, meanwhile a rengar jung goes ape shit on my team thanks to the yasuo hype train bringing out all the good AND BAD players to lock him in because he is op this patch >_>.

But the fact he seems to not have any pushing power anymore, and his rush for trinity feels less impactful than it used to be.

I know the starting paths are usually flask (ie corrupting potion), shield or cloth 4. Max Q W R E

I just need some help figuring out how he fits into the new preseason when so many champs have great mid/ late game scalingswhile hecarim has meh early mid and late it appears. Or if im doing something wrong mastery/rune wise, my pages are hecarim and stampede on account if you want to look.
