Me: "Can I jungle?"
Random: "OH DEER GAWD PLZ NO NOT ON 3V3"
Me: "Trust me, it works. The new map is designed to have a jungler. I understand that it didn't work on the old map, I can even tell you why. But in the new map it's stupid not to have a jungler."
Random: "Ok..."
Wins game.
Gets honored.
Rinse & repeat.
Also I've noticed it's rather easy to get away without having smite. Seeing as how it's more about pvp rather than farming, having a combat spell it better than having smite. That, and smite is usually saved for buffs, and you can't exactly smite steal an altar.
The only thing that smite has a good use for is Vilemaw, and even then you don't need it. Since wards are gone it's easy to take the buff without the enemy team knowing you're there. I also feel like people forget about him. I've gone through several games where he gets ignored by both teams the whole game.
