With the Increase in popularity of Mages in the bot lane..(Champion)

With the Increase in popularity of Mages in the bot lane, I thought why not make a mage who is meant to be a true APC. Someone who slings out spells faster than a 45%cdr Ryze...

never came up with a name for this fellow, as I have for the rest of my ideas.

Passive; Spellslinger. Gain a shield whenever you cast 5 or more spells in a 7 second period, with a 30 second cool-down.

Q; Eldritch Bolt. Medium ranged skillshot with a short cooldown, Dealing (X per level)+(Y AP) magic damage. If Eldritch Bolt hits a champion it is taken off of cooldown.

W; Occult Blast. Long ranged skillshot with a long cooldown, Dealing (X per level)+(Y Mana)+(Z 100% AD) Physical damage. Passing through units. Hitting 3 or more enemy champions reduce the cooldown by 50%.

E; Archaic Flare. Very Close ranged cone(About 1/3rd the size of Morde E) with a relatively short cooldown. Deals (X per level)+(Y Mana) magic damage. Killing an enemy champion or epic monster permanently increases the range of Archaic Flare by a small amount.

R; Spellbound. Global skillshot. Cast a global skillshot, If Spellbound hits an enemy champion they take (X per level)+(Y 100% AP) and are teleported (Z)Units towards the cast location. After 10(maybe more idk how balance works) seconds they are teleported back to their original location and take another (X per level) damage.

So, passive rewards you for landing Q repeatedly, Q can be cast infinitely in theory, if you can land it without any real CC, W is long range harass with a cooldown reset, E is what you want to be using to execute enemies with whenever possible so you can 'Evolve' it into a useful poke/harass tool, and his/her Ultimate is can be used in a lot of ways, Use it to pick people off, if your team is 4v5 you can turn it into a 4v4 so they can either have a fighting chance or run away, what I'm getting at here is, this champ might need to have repetitively low damages, but hi Ulti utility, passive shielding, and Q basicaly being an Auto attack mean he would be able to deal out some heavy sustained damages, while having a pseudo spellvamp with his passive, and, as far as I am concerned, this champion would make one hell of an APC.
