Better stacking for stacking champions and runes

I think it's time we talk about stacking champions and runes, champions such as , but not limited to Nasus , Veigar , Cho'gath and others. The main runs i think need to be discussed are Resolve and Sorcery.

1. Cho'gath . In the case of this champion i would like to see massive changes to his R and his W. i believe it would be much more balances if h could stack infinitely on minions monsters and non epic monsters in the same way that veigar and nasus do. i also think that the % max hp true dmg needs to be removed and replaced with % max enemy hp instead and have it's cooldown reduced by roughly 20 %. as for his W i believe that this ability range and effect duration should be greatly increased but have it's damage cooldown reduced by roughly 50 and 20 % respectively

2. Nausu . For nasus it would be much appreciated if instead of stacking only AD , he could also increase his maximum hp by 2 for each enemy minion and small monster killed but also have the dmg stack reduced to 2 AD per stack.

3. Veigar . I'm unsure of suitable changes for this champion as i have not played him much but i do believe that the rate at which his dmg scales is much to high, his burst is superior to most assassins and his cc is relatively weak in comparison to other mages such as soraka morgana and lux. however i'm sure that a few '' quality of life '' changes can be suggested by other players

4. Runes i believe that resolve's Grasp of the undying should function like sorcery's gathering storm as this would be more balances for champions without ranged auto attacks and strong engaged and disengage ability
