Skarner's objectives should be bigger
Like, it seems pretty useless to me.
Extremely small objectives, mostly covered by walls(even if they aren't in the same place it showed on the map, the jungle is mostly walls and enclosed spaces), that anyone smart wouldn't dare try to go into without their team. If it were bigger, even just the sight radius, it would be 10x better. Vision is super good, I'll say that, but when you can only see 1/4-ish of your jungle its kind of useless, especially if it is in the same place on the map, then you'd see almost nothing but the Kruggs and maybe that one red buff critter. Other then that they can steal your Chickens, or Kruggs if it changes per game, without any of your knowledge. Maybe even red buff, unless you specifically mouse over it to see the little monster fighting something in the fog.
However, if it covered a whole section of the jungle, it would be crazy good. Especially if the enemy jungler is Nunu, he wouldn't dare try to counterjungle you unless he was some super-fed AP Nunu. Even then.
But seriously, the update you're proposing might as well not even be an update at the size it is. It covers maybe your red buff(if it moves, otherwise not even then, and if it does sometimes not then as showed), and then your Kruggs or maybe your Chickens if it moves. Then a slight buff to his MS and AS, so if you somehow manage to get someone in your jungle you can chase them down, or 1v1 someone better, or take a camp or two faster.
