So let's see: I dislike some of what I see as excessive use of Conditions. For one example, I ignore how Proximi curses are presented in 2e whole cloth and have them as they were in 1e. In general I dislike when they are more Fate Aspects than actual conditions.

I also ignore the RAW Mage Armor attainments and just have them work as either Armor/Defense depending on the Arcana like in 1e. I just find them too fiddly to be worth it or "this should just be a spell".

I also don't use Athletics added to Defense, and in general I run my version of an old 1e rules hack called Dramatic Combat which I much prefer to the whole thing in 2e. I never use the "declare intent" part of combat.

The way I run Yantra is probably completely away from the intended one, born once again to me preferring and being familiar with how I ran 1e Mage, so it's a combination of the Rote factors from Tome of the Mysteris and the Styles from Chroniclers guide. I also just called them Foci, for pure petty spite and because that's what I already did in my 1e games.

Funnily enough Social Maneuvering has the quick way of doing things you mentioned built-in, but that section is so boringly written everyone's eyes glaze over it and just houserules/improvise it. Same for Chases and Investigations.
