My only problem with the price change for jungle items:
I dont really think its problematic, I have no problems doing 2 camps (if your jungler lacks sustain, take out crab after buff, it heals you), but my problem is the overall message of this change.
The reason RIOT gave was that it would put junglers ahead, who made an early invade and got a kill.
Basicly that says that RIOT does NOT want to reward risky play. An invade could always go both ways. It was risk vs reward. And Riot litteraly said "we dont want risk reward in our game" with that change. Dont get me wrong here, I enjoy that League is more casual than DotA, thats the reason I play it over DotA, but at some point it just goes to far. And that point is reached when they say that they dont want to reward successful risky plays.
