Singrad, The Winged Terror (Another rework of an older concept of mine)

Singrad - The Winged Terror

Lore: A griffin born of many, his litter slaughtered by a passing Demacian scouting party along with his mother. Singrad hid himself under the broken eggs within the nest and managed to stay alive through the ordeal. Ever since, Singrad has been fending for himself in the wilds, eventually learning how to speak the common language due to his extreme intelligence.

• Will be adding more to the lore later, as for right now, it isn't my top priority, but the basis is the same as my original concept,

Primary Role: Assassin Secondary Role: Fighter

Passive: Predator
> Singrad gains additional benefits as more enemy champions are nearby that he can see and when there are no nearby enemy champions, Singrad regenerates health at triple his usual regeneration.
- 1+ nearby enemy champions: Gain 13~30% attack speed (based on level)
- 2+ nearby enemy champions: Gain 15/20/25/30 (leveling as you level your ultimate) AD
- 3+ nearby enemy champions: Gain 10% cooldown reduction & maximum cooldown reduction

W: Soaring Leap
> Jump and soar over units, dashing a distance based on your current movement speed and then gaining flight. You can stop the dash early by moving, attacking or casting another spell, still gaining flight. While you are in flight you can move over minions and gain additional movement speed as well as access to different abilities. If you are stunned, snared or rooted while in flight, you are forced back to the ground and this ability is put on half it's cooldown. This ability allows you to dash over walls.
While in flight: Dash the same distance but gain twice the movement speed bonus after the dash for 3 seconds before returning to normal.

E: Hunter's Leap/Feral Landing
> Hunter's Leap: Leap high into the sky, gaining additional vision range and the ability to see over walls while being untargetable for 3 seconds. Afterward you plummet back down the the ground. While in the air, you can cast 'Soaring Leap' to dash for double the distance as you glide closer to the ground.
- Additional vision range: 200/275/350/425/500 units
- Cooldown: 32/30/28/26/24 seconds

> Feral Landing: While in the air, you dash up to 200 units crashing into the ground, dealing damage in a radius around you of 115 units and slowing them for 3 seconds. This puts you back on the ground, losing flight. While on the ground, you gain tenacity.

This newest version, I am just changing the ultimate to make it more flashy and not mild and bland and boring.

Let me know what you think.
