I mean if you know your enemy that good, because they are obvious about it and you actually can for some reason play all those items to a level that you can still beat them because those people are "all eggs in one basket"playstyles?

Then punishing them in that way is fine. Thats why those are meme/theme builds.

I think something that people also forget is just how much momentum loss you truly have with an Invocation. In a 1 vs 1 its 9, sure. But you give these 9 momentum to every enemy in the other team over you. (that means the transformation in that scenario is worth roughly 36 Momentum. thats 6 turns. It has to do something very good if it only lasts 4,5 turns itself)

What people are saying here is that Shine knight is barely worth transforming into AS IT IS. So removing something that is indeed very, very good. The negating of light and dark...When that is ALSO no longer the case that people feel that Shine knighting is even worse. Thats why some people say "If you remove negate, give it something else." ...Cause Shine Knighting sucks already in momentum efficency.
And thats without touching how bad the weapon itself it.
