It's not sarcasm. Just because someone says something "based" doesn't mean they're right. It is "based" in the sense that it is an extremely unpopular opinion and this reviewer is extremely unapologetic.

Honestly though, what makes this funny/sad is that this isn't the first time an Ubisoft dev has gotten mad at a new fantasy RPG - these people (same guy?) had a similar reaction to elden ring which also broke records and went against industry norms. These "norms" have been terrible for gamers because they've allowed publishers to claim that they're making "better games" just because they managed to squeeze out a little more graphical fidelity since the last iteration. Then an independent dev comes around and shows the world how utterly incompetent these mega-publishers are, and their response is to cry and spew nonsense about how "real games" are supposed to be.

Turn-based as oppose to realtime-based combat. You take turns with your opponents picking a next move. Realtime there is no waiting for your opponent to finish their turn.
