Druid champion Idea for LoL

This champion is based in my favorite class of World of Warcraft: the Druid. There's already a "druid" that is Nidalee but does not give the same feeling. With this champion, you could play in 3 differents lane and in 3 differents ways with his 3 trnasformations/shapes. A transformation that is a Human, which would be supportive; Bear, which would be tanky and Werewolf, which would be DPS/Burst. You can transform in few seconds, and this may be broken, that's why I did the emphasis on giving it scalations and not base values, so if you go wolf, you scale with AD and the healing of human will not be worth it (humans scales with AP and is a progressive healing, so not useful, you would be losing DPS) and tanking scaling with Additional tank stats like Armor, DPS and Max health got by items.

[ Additional ]
 - Starts with one point on R + the one player chooses
 - If player wanna go supportive must play Human almost all the time. Humans abilities scales with AP, so Werewolf should not be big deal
 - If player wanna go Tanky must play Bear almost all the time. Bear gains Armor and MR with his W and healing progression scaling with Additional Max Health
 - If you wanna go Damage must play Werewolf. Werewolf scales with only AD so no human and tank form will work much.
 - Basic abilities (Q, W, E) can get 5 points of level; Ultimate (R) gets 3 -> 18 levels (3x5 -> Basic abilities) (3 -> Ultimate)
 - In theory he can play in 3 roles (this may be broken)
   - Jungle -> With Bear Q he should be able to clear camps and tank camps with the W and heal if he gets too low. He has a frigthening that should help at ganking
   - Jungle -> With Werewolf E and Q should be able to clear with no problem, also W could help in ganks
   - Mid -> With wolf E that gains damage in area and having a bit of lifesteal should make OK the laning phases. W helps him to roams
   - Support -> With human W can apply a buff that heals overtime, can also heal more if Q is hit. Has a bit of Poke with his Q and a bit off CC in area with his E
