Ideas for New Champion

I have an idea for a new champion, A Shaman. His Q is a totem that slows nearby enemies and remains active for a certain amount of time or until killed. His W spawns a totem that throws out a heal that jumps to one other friendly target. (optional)Make it balanced by not having it target champions so you can't be sure you'll always get the heal(optional). His E Is a totem that lobs out a fire ball every so often in the nearest enemy's direction that his the ground and does AEO damage in the form of a lava pool. His ult is a heal that bounces from champion to champion like a brand ult, healing his allies, including himself. His passive should either spawn a random totem or give him the ability to recall totems for mana depending on totem remaining health.
