Orianna is a lot of fun. Just got done with a game as Jarvan who I never play as because I'm terrible with him. Went 6/2/1, stole 3 blue buffs, solo'd 2 dragons, and man-moded everything. His E-Q isn't that hard as long as you time it around them going for a last-hit. The Knock-Up line extends a bit further around the flag too so it's bigger than you'd figure. The Poppy I was against ran ghost so every ultimate was the Demaciest.
Just tried out Jungle Jarvan in a game and holy. shit.
Spoiler for Man Mode ahoy:

I know what you're thinking and you're wrong. Renekton did not 2v1 top vs. Alistar and Tryndamere.
Ezreal did, so I ganked there right after blue and got first blood on Tryndamere because Ez was dying. Fast forward a couple minutes as I finish my jungle clear and Ez gets a double kill top, Tryndamere flips his shit because he forgot Ezreal had an attack speed debuff, I laugh my ass off. I think he and the renekton were buddies that worked that out, it was pretty genius. This is definitely a game that went extremely in our favor because Tristana disconnected, they had no jungler and took 2 of their buffs the whole game, and I got fed as fuck on their jungle and their delicious corpses. No idea what the hell Alistar was building or if he sold what he DID have for that because they were kind of hating life at the end of that game. That Zilean was super bro and counter-ulted to Karthus a bunch which was hilarious.
Times I recalled:
1) Bought Wriggles (started vamp scepter)
2) Bought Merc Treads
3) Bought HoG and Phage
4) Bought Warmogs
5) Bought Trinity)
6) Bought Atmas
all raw-buys. manmode HOO-AAHH.
On Jungle Jarvan himself, I really like the way he feels and I LOVE his mobility through the jungle when he has blue buff and can just EQ and be Spiderman all over the place. Good way to sneak in a solo dragon if their ward can't see dragon or there isn't one.
