Infinite Stacking Champions Need to be Capped.

In a recent match against one of the infinite stackers (nasus) who essentially after a while can fight most of the team if he wasn't stunned or rooted. The problem with nasus as well as the other infinite stackers (Veigar, Sion, Chogath) is that, the longer the game, the more they can stack and the more impossible it is to fight them when they get ridiculous damage from these stacks. The problem is the stacks without restraint. If its possible for a Cap on the stacks, it might be better and the word "balanced champions" wont be used as a joke of the company's modo. The cap SHOULD be high enough that they can still help their team WITHOUT becoming useless as the match goes on.

Now the problem. How many stacks for these infinite stackers is "high" enough? The rate of stacks on these champions are different and for different stats, how would it be "balanced"?

For nasus, i believe around 500 to 600 cap is healthy enough. plenty of power to destroy champions and towers (300 already chunks towers) with but now has to work with the team to coordinate team fights instead of, click Q to win or walk and take all the damage and brush it off like a teemo dart lvl 1.

Veigar is a little more complicated. All his ability's only go up 1 for each champion hit and up 1 every sucessful Q minion kill. then kills and assists give him +5. For veigar, I believe his stack cap would be 300 minimum/(max)-400. Usually by the time Veigar has 300 stacks worth has already god with proper items.

Chogath. He's one monster when his stacks= health that count towards TRUE DAMAGE to champions. 1 combo (or a Q, W, R) and another one bites the dust. There are many problems with cho, has an amazing sustain in lane, once he is rolling its hard to stop him. I would of liked to remove his true damage, but seeing as Lethality is a thing, that is not plausable anymore. Honestly the only thing i can think of is reduce the amount of true damage he gets for his health. :/ honestly i do not know what would be best to fix cho's stacks.

Sion mainly just gets more health and his w acts as shield and Axe. The health cap i think would be good (and maybe impossible(?)) to reach would be 1000 bonus health max from stacks. Now im not a sion main so unfortunately im not completely sure if this is even viable of a cap. Im not too entirely sure for sion but thats roughly what i can think of for his stacks.

Thank you for your time to read this and let me know what you think.
