Saw it after I posted. Then I can make no sense of what you wanted to tell us then, because Flamestrike was pretty clear that he was speaking about delaying a single class by multiclassing and that he usually considers it underpowered compared to the single class. In the part you now quoted, he explicitely stated that delaying the sorcerer levels is usually not worth it, which we both seem to agree with.
I'll try to explain. Sorry if I misgender anyone:
Flamestrike posts about MC casters being envious of single class casters.
I agree with his post.
Flamestrike says martial characters have the same problem, when they delay extra attack.
I joke about delaying spellcasting being a bigger loss than delaying extra attack.
You talk about delaying extra attack by 5 levels.
I joke (again) about delaying spellcasting being a bigger loss than delaying extra attack.
Flamestrike says extra attack is a big deal (for martials) because it's an exponential increase in DPR.
I argue that damage is less impactful than spellcasting, because spellcasting is effective across multiple pillars.
Flamestrike says he's talking about delaying paladins with a one level dip.
I try to clarify what I'm talking about (MC casters being envious of single class casters, etc)
You said I was answering a conversation about paladin multiclassing.
I link to where I clarify what I'm talking about (MC casters being envious of single class casters, etc).
You say you don't understand what I'm talking about.
I write this post to explain what I have been talking about.
Hope that helps!
