When you burn torn husks, torn marrows, or torn sinews to increase pestilence intensity, you get maximum 4 level of corruption but get rewards as for 10. I do not think it should work that way.

This is entirely by design. Burning these (valuable) materials allows you to gain increased rewards with fewer difficulty modifiers.
(It’s even encouraged in-world – the Watcher and Roan talk about this.)
Wow, thanks for the clarification. It feels like an unfair oversimplification though.
are you really sure about that?
You can only get those materials through killing mobs and bosses inside the Pestilence outbreaks.
The only other source you can get materials from is The Watcher who only is an Exchange Vendor, so you still need to have gotten Pestilence Materials from a Pestilence outbreak in order to take advantage of the Exchange function?
I actually Agree to that statement in a sense where i believe it shouldnt give us 11 Sinew and 6 Marrow for only burning 8 Sinew and that is only counting the Rewards you get from killing the boss, and then you can also get additional Pestilence materials from killing mobs before the boss appears.
Maybe I just played lategame too much. I have tons of torn things and spend them to gear upgrade too rarely.
I think hard debuffs should not be simplified as long as it is your choice to get them.
