Junglers level up a bit too fast, now a stale meta.
Fast level 2 from 1 buff. Rift, gank, tax some exp hit level 3. Backs to buy, 350 gold nets you your second jungle item that blows everything else out of the water. Level 4 with jungle item or 5 with good ganks -> Extremely safe dragon.
I play Udyr.. so I rush Triforce too. This also gives me very fast.. tower takedowns.
I used to be a mid laner, but now Top and Jungle have so much pressure to carry (look at all of the top challenger players) they have so much power on whether or not you win the game.
Because losing top = lose half of your buffs.
Why gank bot lane when you can snowball top.. then just simply push bot lane with your advantage?
1-3-1 set ups are common now because of this, and its boring.
Not gonna lie; I would LOVE to help my team and group mid randomly for 5v5.. but I take towers extremely fast and can clear objectives without the team now. 5 man teleport play bottom? Good, free rift and two top towers.
5 man roam top? Good I'll just take dragon and another bottom tower.
Team playing from behind? Enemy constantly with a 1-1-3 or 3-1-1 set up that is literally impossible to play against.
