Do NOT give garen and mundo this set of buffs
The last thing statball champs need is more numbers/raw stats.
What you should do to them is give them mini reworks and increase the ability they have to interact with their opponent, both as in outplaying and getting outplayed.
Currently mundo and garen are simply a running : You have more stats than your opponent? You win, You dont? You lose.
You should NEVER give raw stat buffs to champs like that, have you learned nothing with the years balance team? The fact that those changes are even being considered is laughable.
