the EA is also missing a lot of content that isn’t ready yet
Sure, but there’s also plenty to explore, especially for people who haven’t played PoE1 and have to learn how things work from scratch. Given you don’t pay extra for EA and premium stuff like stash space you buy goes to both PoE1 and 2, you get quite a bit for your early access ticket.
But probably more important that early access characters and stuff aren’t available out of early access, so you are explicitly playing temp characters. Fine if one treats their early/seasonal characters as temp characters anyway, but someone else might not want to play characters with no future after early access.
Gameplay has been so on the decline nowadays, that just having an actual reactive counterplay element like a parry is a major positive, even if it’s a huge simplification of defense. So, more engaging defense mechanics would be nice, sure, and there’s certainly huge underexplored territory on “offensive” actions with non-universal parry type defensive properties to make fighting more interesting, but that doesn’t mean what little we do have becomes a negative or less engaging.
It was tragic that the current Soul Calibur dumbed their deflect down to a single simple action instead of the series standard of at least needing to match low/high height zones (mids could be deflected with either, which was a nicely subtle drawback), but it’s still better than not having it at all.
Parrying is good. More interesting parrying/defense is better, but that’s a level of player and dev effort/investment that’s rarely on the table.
