So all that stuff about how the dex save bonuses and zero vs half etc never, almost never, mattering etc are more universal findings, not just limited to that table/character canpaign and the folks talking about how useful those are in other games are wrong?The feat is intended primarily for fighters, paladins, barbarians and clerics. Dwarves are pretty popular for that subset of classes. Given dwarves are one of the very few classes that can get a bonus to strength, and sword and board is going to be a strength based build most of the time, it's going to be rather common for a dwarf to be the one fairly likely to be wanting this feat...until now that is. If they push with the feat and move 25 feet off, their foe will just close again with a 30' most of the time. If on the other hand they shove with the feat to make the foe use half their move to get up, the foe gets an opportunity attack. It makes escape somewhat easier (the opportunity attack at least is at disadvantage) but escaping is not really what you might describe as a primary element of this feat.
And no, I don't think this is really such a narrow topic as to reduce it down to just his table. If one of the most likely races to be selecting this feat is also the one that loses out on the escape benefit you're prompting, it's certainly in the topic of discussion beyond just his table.
Or is it just that the negatives are ok to extrapolate to other tables but the positives have to occur at that one table to count as a rule for this thread?
