elementrax - god of frost fire and earth ( please give comments on your thoughts)

Someone posted a request asking for ideas for an elemental champion. I was thinking about this and decided to take a stab at it. So here goes my third champion idea. No one liked my last one.

Name: Elementrax

Q: Elemental Throw Based on the element currently active Elementrax will throw out a straight line skill shot dealing 50(+50% AP) damage to all targets in a line. Depending on the active element a special affect will occur on hit Frost – Any target his has decay slow on it for 25% move speed for 2 seconds Fire – Any target hit is ignited for 2 seconds for 5% of damage on hit. Earth – Any target hit is knocked back 25% of the distance the projectile traveled

W: Elemental Summoning Orb Elementrax summons an orb to that has its own health bar. Frost Orb – Targets take 10% of AD as true damage from Orb’s attacks. Fire Orb – Targets take 10% of AP as magic damage. Earth Orb – Targets have reduced armor and magic resist by 2%. Stacks up to 3 times, refreshes each hit. Debuff last 2 seconds.

E: Elemental Path / 50/75/100/150 Mana Upon activation Elementrax creates a trail of the current active element behind him. Frost Path – Elementrax throws a path of ice in front of him giving him a 50% speed boost for the length of the path. Fire Path – Elementrax throws a path of fire behind him that sets all targets hit on fire for 50% of current AP that is spread over 5 seconds. Deals 20% of current AP as magic damage. Earth Path – Elementrax smashes the ground around him stunning targets for .75/1/1.25/1.5 seconds. R: Elemental Shift (starts with 1 point in at lvl 1, 4 points max for it) No mana to shift (3 second cooldown between shifts)

Passive Every point into Elemental Shift unlocks a new element to use. 1 point in it gives frost (Starts out with frost) 2nd point gives Fire and 3rd point gives Earth. The 4th point increase all damage caused by active element by 10%. (NOTE All of elemtraxs varations of elements amongst skills have separate cooldowns.) (I.E. Elemental throw is used for frost and then you shift to fire element and those skills are off of cooldown. Similar to nidalee and jayces ultimate swap timers)

Activate: When elementrax actives Elemental shift he throws down an orb that represents each currently available element to shift to. Blue for frost / Red for Fire / Green for earth. Clicking on the ball will trigger the new shift. Current element wont be clickable.
