Dimension Controller Mage concept

So i've been playing a rather unpopular mmorpg called Kritika, and they had a class there which blew my mind. So if possible I would like to have a similar idea implemented into LoL. The concept is of a mage wielding a gun. In Kritika as a mage you can choose to be an ice mage, shadow mage or a dimension controller mage. The last one is imho the most amazing and awesome one, and you could check it out here:

I mean, how cool is it to be able to make black holes which suck people in?

I have a feeling that this could potentially be the younger version of Zilean.

I would imagine that giving him the ability to teleport around quickly, deal damage and be able to perish into thin air right after would make an awesome mage which currently doesn't exist in league.

This is just an idea, and I would love to see what other people think about this concept? Also would love to hear some ideas about what kind of skills you would like to see on him? If at all?

EDIT:

How about basic attacks where he shoots the target with an invisible bullet, causing an effect similar to Soraka's old Starcall? Meaning when he uses a basic attack, instead of the old fashioned "shots coming out of the user's hand/wand/gun" his basic attacks are blue stars/meteorites falling from a different dimension? That kind of a basic attack would be really unique.

Name: ?? - The Dimension Controller Role: Mage/Marksman Main attribute: AP Statistics HEALTH 574 – 2100 ATTACK DAMAGE 55 – 107 HEALTH REGEN. 5.4 – 16.8 ATTACK SPEED 0.658 (+0% – 70.1%) MANA 326 – 1091 ARMOR 23.9 – 78.4 MANA REGEN. 8.0 – 18.6 MAGIC RES. 30.0 RANGED 550 MOV. SPEED 340

Passive:

Meteorite - 17%/18.5%/20% of AP is added to your AD. Fastforward - ???'s move speed in increased by his attack speed (( Ratio of 2.5 his attack speed. )) *-missinggrave *

Q: Epoch - ??? is granted a passive 5/10/15 move speed boost. Active - ??? Shuts out a desired area in another dimension after a .5 seconds delay. Roots enemy units in place dealing magic damage (( 1.0 AP )) to those caught in the AOE. The root lasts 1 second. Base damage: 50/75/90/125* -missinggrave *

W: Time&Space Shift - ??? Creates a rift through which he may travel to a short distance. (Teleport) Cooldown: 10/9/8/7/6. If ??? uses this ability next to an ally or an enemy champion, he may cast it again for free. (Similar to ez/kass blink but this skill does not deal any damage)

E: Galaxy Wings - ??? Gains wings which give him bonus attack speed and the ability to attack up to 2/3/4/4/4 targets at once, dealing bonus damage in magic damage per hit. (This is a toggle skill which grants temporary wings for 5/6/7/8/10s. Does not prioritize champions and deals only 50% damage to nearby enemy turrets when they aren't directly targeted)

R: Supernova - Close range, large AOE spell that pulls in enemy units and deals magic damage (( 1.0 AD // 1.5 AP )) to those caught in the blast. Those in stealth will be brought out of stealth, this spell creates a wide area of true vision for 5 seconds, and slows enemies caught in the blast by 5/7/10% for 2/3/4 seconds. Base damage: 250/400/650 (Damage over time) *-missinggrave * R: Passive - When Supernova is activated, ??? may use his W freely at no cost or cooldown while inside of it.

LORE: There was a great city in the wastelands of Urtistan where sorcerers and humans shared daily lives together. One sorcerer would really stand out, and that was the Dimension Controller. No one really knows where he came from, but one day he suddenly appeared in the city, bringing knowledge and new power with him. A power which granted him the ability to manipulate both Time and Space, so commoners have never pondered about his origins since he "probably came from another galactic." As time passed, he started noticing that his ability to control Space began leaving him. Before he would fall into despair, he began using all of his abilities to manipulate time and reverse it back to when he could perfectly use his abilities to the fullest. After retrieving four of his abilities he rushed to the League of Legends, where a powerful summoning magic employed by the members of it would ostensibly help him. After being unable to find a way of retrieving his powers to control Space, he left the League of Legends and rushed back to Urtistan, only for him to find out that it perished long ago in a terrible war. He fell into despair - causing him to lose his remaining powers as well as his memory of who he was before arriving there. All he could think about now was to find a peaceful solution to this horrendous war. Being obsessed with time, it was only fitting that he dwelled in the city's Clock Tower.
