I have nothing against 4e, never played it, never cared. I returned to TTRPGs sometime during 5e after leaving during 2e. From all I have heard it is a good wargame, but no good D&D game (too different), I have no particular reaction to it however, at most it is some intellectual curiosity
If 4e ‘always’ triggers those kinds of responses with some people loving it and others loathing it, then it simply is divisive.
My reaction here was purely to the bland text presented and the claim that the 5e Fireball should be more like it, not all of 4e. I entirely disagree with what was said about the 5e Fireball, the rest just followed from that and is not about 4e but about what TTRPG text should be like. No need to try to make this about 4e
