Please please please make the knowledge of the Mutant Ogre & Mutant Troll obtainable some other way than killing these two outdated bosses!

Making them an option to obtain via amnity with some NPC would be my suggestion. 

These bosses are rarely ever killed due to their massive HP and useless loot drops, and even if they are only one person will get the knowledge. 

It's been years now and this is so triggering for my OCD when trying to complete all the knowledge - please PA do something about this!

As a knowledge hunter I fully agree with this suggestion.

Yes, I totally agree.. knowledge of these should be made easier to obtain.. atleast through Amity from someone. 600 Amity would be a decent amount to start with I think.
