Ideas for Nunu Rework

First I would like to apologize for my English.

The following proposals are tentative, the most important is that they can lead to other, better ideas, but I hope to serve for the (near) future change in Nunu.

The idea is to make a character scale to the end of the game have much impact if not fought against (colossus in the jungle?).

Passive: the great monsters of the jungle get 2 points, small one, to reach 15/20/25/30 you have a goal: kill / assist a dragon, herald or Nashor baron.

If you succeed you get an improvement in a skill (in order?), You gain size and + 5% / 8% / 11% / 14% additional maximum life.

Q: Damage to a monster / minion and you heal.

To choose one: Q1: (Bite) You can use the skill on enemy champions and do a magic damage and leave a mark on the floor with blood (Q Nocturne) or slow Q2: (Glutton) If more than a monster / minion makes 70% of the damage to all monster / minion that are within a small area. Q3: (Cannibal) Adheres to an enemy champion and hurts of channelized way (as Skarner but the enemy chooses the direction). You can be interrupted.

W: PASSIVE. When Nunu in combat earns up to 5 stacks that provide movement speed (1% / 1.25% / 1.5% / 1.75% / 2%) (hence maximum 10% at level 5 skill with 5 stacks) by mark and speed attack (2% / 4% / 6% / 8% / 10%) (50% maximum level 5 with 5 stacks) by mark. It decreases accumulation per second after three seconds without a fight.

W1: (Bloodlust) While pursuing an enemy champion not decrease accumulations. W2: (Explosion of anger) A actibable skill becomes. It makes you get 5 stacks at once, but decreased after 3 seconds without fighting. W3: (Rancor) You can have up to 8 accumulations.

E: Snowball as skillshot. Slows the enemy hits.

E1: (Mark) If it hits, can re-use the skill to move to the target (as in ARAM). E2: (Ice) Stun. E3: (Rain balls) Slows in a small area and launching becomes like a Q of Ziggs.

A: Nunu will progresive damage to enemies that are inside, the longer they will receive more damage inside (like the pools of poison in Diablo 3) in an area like the current

R1: (Frost Wall): Creates a barrier around his circle (Jarvan R). When interrupted will stop hurting and the barrier will melt 2 seconds later. Damages enemies as it does normally R2: (sticky Ice): The enemies will see his movement prevented. Besides slowed they may not use jumping skills / displacement. (Cassiopeia W). Damages enemies as it does normally. R3: (Nova freezing): Nunu channels and slows as it does normally, but a second into which channels there is a Varus Poppy Q or R type indicator increases. When finished channel will create a wave of damage that slow / stun enemies considerably.

Regarding the R could work on concepts that were different each option: create a combat arena to help improve the allies (movement speed / attack ..)? Do we channel one breath as the Q of Varus but the dimensions and shapes that slows Nami R I freeze?

Also on the W you can work, maybe an active to share the with an ally if you have 5 stacks?

Or perhaps a change completely and become a new Kled.

It is the way it is ideas, I hope you liked it and serve to enhance this character.
