Champion Concept: Natures Folly

when I get bored I like to deisgn some champs and abilities and this is one I felt could be fun, Ive wanted to create a support based champ around a zone, and I have always wanted to doa healing fountain kind of champ that is particularly strong in a zone he/she sets up, so if you guys like it I will try to draw some concept art and maybe digitially create their abilites in actions or something I dont know, you tell me how the concept sounds.

Passive - mother nature Every 30 seconds the next autoattack deals X percent damage over time and if it or an ally kills target enemy while the dot is ticking, a small tree spawns where the enemy died and will hit all enemies within a small radius, if target was a champion, the tree will roam around an hit target enemies.

Q autostarts and when activated places a small AoE pond/well thing that looks natury and heals all allies in the pond for X every few seconds and can be replaced every 4 minutes. While placed Q can be toggled on and off and drains mana per second. while on, Q will slow any enemies inside the pond.

W- W cause trees to grow, they arent sentient and only act as impassible terrian in the area around the pond

E- Causes the pond to stop healing and fire erupts from the pond burning all enemies within for X and causing all the trees to burn down and enemies near the trees take burn damage as well as get stunned by any trees that fall on them

R- Causes all abilities to be enhanced, and nearby enemies wil be rooted and dragged towards the pond. If the healing is active, allies heal faster and get a shiled, trees summoned will become sentient and roam, and finally if the fire is active then itll cause an explosion when activated knocking enemies back and dealing burn damage
