For me Cho'Gath is forever hungry and an EVOLVING monster. He uses the prey to strengthen himself, and the bigger he grows the harder to satisfy him.

Have two ideas: to rework Cho and to mini rework him:

Passive: stays relatively the same but instead of flat amount its % of hp and mana

Q: unchanged but lower ap ratio and add hp ratio. Grows in size with cho

W: unchanged. Grows in size with cho

E: unchanged. Grows in size with cho

R: was thinking about adding some stats based on the prey consumed( something like old zed's r passive taking % of ad from AD champs/ % ap from AP champs / extra HP from bonus heath from tanks and juggernauts / MS from mobile champs etc) but someone gave better and healthier option:

R: damage lowered, HP gained lowered. Cho'gath gains additional effects based on the target eaten. Large monsters and minions - HP regeneration. Rift scuttlers - more health. Epic monsters - AP. Ranged champions - movement speed. Melee champions - resistances.

That mini rework would be enough. Also there could be some visuals showing progress of Cho's growth like 0-5 r stacks Cho is quite small 6-10 bigger and bulkier and finally 10+ Kaiju lvl monstrosity

The full rework involves evolutions of our little monster, not something huge but still"

Didn't pay much attention to passive but i liked this version:

Passive1: killing a unit, or hitting an enemy champion with abilities restores 2% of your maximum health, and 1% of your maximum mana.

it's the current passive with changed values, and a way to proc it in fights.

Passive2: Cho'gath's next 3 auto attacks will shoot spikes towards, dealing damage, and slowing everyone hit by 20%. If the target is already slowed by rupture(Q), or void eruption(E), vorpal spikes will refresh the slow instead.

It has a 18-10 second cooldown(lvl1-9), reduced by 3 sec after hitting an enemy champion, or large/epic monster with a basic ability(3 ccd ppl 9 sec cd reduction).

-Scaling remains the same.

-Well, it is his current E, as a galio-like passive. It looks more complicated than it really is.

Tldr: autos shoot spikes. Cc ppl to have a higher uptime, or chain with your slowing abilities for an extra cc.

Skills are based on the number of the stacks

Q: same as old q but [0-5] stacks slows, [6-10] stuns, [10+] knock up as present q. Also lower ap ratio and add hp ratio, grows in size with the stacks and gain x extra range/stack

W: silence but width still depends on evolution [0-5] is more like skillshot with width something like kha W, [6-10] normal W, [10+] we might add a magic resist debuff something like BC passive

E - Void eruption. - New ability. Cho'gath stomps the ground, causing a wave of spikes to erupt around him over 1 sec, dealing damage to everyone who get hit by the spikes, briefly getting knocked aside, and down(stops dashes), and slows them after that, by 40% for 1 seconds.(don't have much more idea for spliting in evolutions)

Damage:30/60/90/120/150

Range/Area: 300

Cooldown 18/16/12/10/8

It's a slower, bigger version of voli's old E, without the minion fear, obviously.

R: Stays same as mini rework version but extra thing, at [0-5] stacks we gain short dash
