I actually did not enjoy how the mythic powers is integrated into the main story of WotR it felt like as if I am watching an anime (cheap basically)
-Might be a spoiler so don't continue reading -
when there is no hope of survival and out the sudden a mysterious power comes to aid the party (not just the mc) lol mechanical-wise they sound great but story-wise I am not happy with it
everyone has a different opinion and i respect that.
for me personally, WoTR was truly heroic and glorious. i first played the Angel mythic path. and i salute owlcat for their musical score. it connects on having the feeling of righteous in it. basically WoTR is based on the Pathfinder Adventure Path. so i believe they are staying true to the original storyline from Paizo.
i completed WoTR EA and basically i'm not going to spoil it. I find the story quite interesting personally.
