I would also add a controversial opinion. WotR (and other RPGs) do reactivity better than BG3.
While BG3 has a lot more reactivity for even compareable mundanes things like your race or class (although Arcanum already did that much better), the effect of that is rather limited. Basically your race/class allows you to replace one skill check with an automatic success. WotR on the other hand does not really react to race or class, but the reaction to your mythic path is huge and not only alters companion interaction but also parts of the plot. And I do not only mean things like the Swarm that Walks that forsakes all companions and allies and devours everything in its path with its clones, but also "normal" paths like Lichs who raises slain enemies as undead companions, Aeon who completely changes the plot by time traveling back and preventing events from happening. And there are also smaller things like how the Azata has to free Aivu from the slave market and has personal scenes like the round table with his mimic knights.
Sure, just being a specific race or class in BG3 should not have that extreme consequences compared to your choice of mythic being, but I would have expected to at least some race/class specific quests or having some "we don't serve your kind" moments where some races have to approach a situation differently than others instead of just automatically succeed on a skill check for the same result.
