Unique Feast Stack Bonus for Cho
So, I thought it could be interesting to grant Cho boni depending on his Feast stacks, backing up his size with fitting addition. The health bonus might have to be reduced, but I really feel like this might make him more unique.
1 stack: Nothing 2 stacks: Feast heals Cho for 25% of its damage. (Well, it's a Feast!) 3 stacks: The range of Vorpal Spikes is increased by 125 units. (Obviously his spikes grow as he grows!) 4 stacks: Cho gains 6% movementspeed. (Larger legs!) 5 stacks: The duration of knockups is halved. (That guy is starting to get heavy!) 6 stacks: Cho'Gath gains resistance to knockbacks. (Ever tried to push a truck?)
Again: His health might have to be tuned down slighty to compensate for these additions, but I really feel like they thematically fit his feast & growth concept.
