Yes, this should have replaced Rengar. Now I am *yawning* at another stealther plus jumping PLUS slowing. Was kinda hoping for more of the Alien feel.
Passive: Returns a percentage of basic attacks back to attacker, this stacks with Thornmail. If you have not died in the last 5 minutes, you gain a Cocoon at base. This allows your next death to have an instant respawn time.
Q-Evolutionary(passive): Increase your vision range, armor, passive and movement rate.
W-Spike Tail(toggle): Each of your basic attacks cause your tail to attack a random enemy, favoring champs. The tail activates on-hit effects, has increased critical and drains mana per hit.
E-Speed burst: For a brief time, double movement rate and attack speed. For a few seconds after, your attack speed and movement are reduced to a small fraction.
R-Unforseen Arrival: Can activate to 'jump' to nearby locations, becoming stealthed while doing so and making an attack when arriving, tail included. When in cooldown, will not show up on minimap, even if in combat.
Something like that would have been much more...alienish. This just looks like a mantis guy, but now that they made him we are never gonna see a Xenomorph...sad panda.
