Cho'Gath range inconsistency

I'd just like to point out that Cho'Gath's attack range is greater than the range of his R - Feast at -/9+/7+ stacks. Though a small range difference, 33 at the most, this results in Cho'Gath being able to attack a champion but not be able to eat them without taking a step forward.

It can be disconcerting to play because a champion will only walk to the edge of their attack range after right-clicking an enemy champion. For the majority of the game (hopefully) a Cho'Gath will be able to do a combo of Q -> E -> walk up and attack -> R but after enough stacks there will be a slight delay before the finishing blow or the Cho'Gath would have to walk slightly further than necessary to perform his basic attack.

There are several easy solutions to fix this inconsistency:

1. Increase the range to be Cho'Gath's longest attack range. This is a straight +25 range buff but is simple and clean.
2. Make the range be the maximum of 175 or his attack range. This only buffs Cho'Gath when he has gotten those extra stacks to keep his play consistent.
3. Make the range of his ultimate tied to his attack range at all stack levels. Perhaps Cho'Gath's neck is only so long, say, 25 units. The range of Feast could be his attack range +25 so that it always was a little bit longer than his regular attack. This would reduce the range at 0 stacks but increase it as he grows in size.

Hopefully this mechanical hiccup can be cleaned up so we can much away without worry. Thank you, -Vulfi
