URF MODE: Where Every Champ is OP As Fuq
Please post any champions you have played and why you feel they are OP. I'll start, since I only played three games:

- 20 Shrooms
- MARKSMAN so much faster autos which apply poison
- Q is up every 2 seconds so if you keep spamming Q the enemy can NEVER AUTO ATTACK YOU. Let that sink in a bit.

- Q is up every 1.5 seconds or so and allows you not only to deal AOE damage but to dodge EVERYTHING, even tower shots
- If you get a single kill or assist, your R is ALWAYS up. ALWAYS. Did I say ALWAYS?
- No mana so free heals/shields VERY often

- Stun is up every 2 seconds with rotation spam. As close to perma stun as you can get in this mode.
- Tibbers if not killed is ALWAYS up since he is on a 24 second CD and lasts for 45 seconds...you do the math.
- With flash up every minute she has possibly the best engage in the game now.

silence, knock up and burst for those pesky squishy, sustaining blinking champions. W-Q-W-R combo destroys everyone. Your Q is off cooldown before it even erupts.
JUST DO NOT PICK HIM IN URF
and
. Galio's shield lasts longer than the cooldown, so even at rank 1 it's permanently on, his q and e already give him great chasing potential in normal games, in URF it's a lot of fun, and his ult is up every 30 seconds or so. Yorick can spam ghouls so that he always has the lifesteal ghoul up. Managed to win a couple of 2 v 1 with Yorick vs
and
. Once even had 2/3 health Aatrox lose to 300 health Yorick...because lifesteal ghouls.

Haven't gotten a shot at the current URF, but I remember going 1v5 with him and getting out with a kill multiple times. A taunt, a shield and a heal make for a potent combination.
Use the Legolas build
That's MY health now
heals and Q damage for days
Go AD and eat towers
Boxes everywhere

Q spam
Spam spells from base
kite forever
has the strongest level 1 with endless bodyslams, and eventually his ult constantly helps you catch people out. The slight "issues" with him in urf is using your w before entering the fight, due to its channel time, and you can't really let your q charge up. But the body slam is all you really need, in the end.
surprised no one mentioned him. His q has a 1.8 second cooldown, and his dash is 2 seconds at rank 5. w is always up. No one escapes and few can duel you.
her shield and Q are pretty much always up, get enough AP and you are not going to die
Spell shield op, Level 1 poke/harass/waveclear is godlike, and her ult is on such a short cd you are pretty much always able to give a strong speed boost (Hecarim loves it too)
