Grim corruption and corruption in general

I would like to say that grim corruption + the game normal corruption mechanics is very very bad thought out and comparing to V2 where u had a fix amount that can be future reduce with items this one … well it sucks balls, you will end up getting 1 shooted or instant death super fast specially on higher difficulties because of the stupid amount of corruption you will get.
Grim corruption needs a fix i can thing of 2 types.

1 set a max % like in V2.
2 give no set % but make it so when you get hit the corruption will go up faster then normal here is some examples:
NO Grim Normal hit 5 HP dmg + 1 Corruption
1 Grim normal hit 5 HP + 2 corruption
2 Grim normal hit 5 HP + 3 corruption
