ToME: the Tales of Maj'Eyal

I believe that Light tree is just way better than any other possible reward you can get from escort trees and should be replaced with hymns.

In the same time worldly knowledge should go away from its "insurance against the bad luck" prodigy and actually give good unlocked 1.0 mastery trees that can't be obtained from other sources or not available for all classes (like mobility for casters)

This change is terrible for classes that need Light like Necromancer, Demonologist, and Reaver. Corruptor, Archmage, and Alchemist are arguably hurt too. Half these classes are already severely lacking as it is so this is an unnecessary nerf to them. We may as well completely remove categories from escorts if you want to delete the only one worth taking.

Sounds like there's room for a defensive generic tree more thematically in line with necro/vim classes beside Vile Life, IMO.

If this change is going to unfairly ruin specific classes, then those classes need fixing.
No class should be relying on a randomly obtainable category.
I don't support removing Light from the escort quest rewards though.

I agree HousePet, but Light can be thought of as a placeholder until Necromancer and other classes get decent replacements. Removing Light without fixing these issues would be very bad, but after they are fixed it can be worth discussion. That said I don't agree with removing it regardless.
