Cho'gath rework

So recently I filled out the Community Feedback Form and it asked me " what champion do I feel needs an update." It took me awhile as I was pretty happy with the kits of the champs I played. But then i thought about it. Cho'gath needs an update. I began thinking up some ideas and here they are, go ahead and share thoughts as well ;)

Replace mana with essence, drawing influence from Dehaka from Heroes of the storm. His E, Vorpal spikes could be replaced with "consume" Cho'gath consumes all essence, increasing max health and size (slightly). The bar might have 10 stacks. Large monsters and siege creeps would grant 1 essence, champs, dragons and herald grant 3, and baron and elder grant 5.

His ult could be changed so that things killed by feast grant bonus essence.

Feral scream is ok but I feel like rupture should be changed. maybe he could shoot spikes up from the ground in a straight line in front of him, similar to kayne rahst W. Go ahead and share thoughts...[slayer-jinx-wink]
