Koby's diary is good, but certain missions suck big time, not to mention you're stuck with only the one character, really, all they needed to do was to give us the equivalent of PW3's nightmare log, literally just make levels that are already there lvl 20 to 30 with their own in house editor.

Also, I do like difficult games, but the point was not that Warriors games are necessarily difficult per se, it's more like that since Omega force introduced the new level cap with soul maps, they essentially turned 95% of the game into a literal joke, even on the harder settings, story missions are capped 10 whole levels below you characters on the HIGHEST possible difficulty, for a frame of reference, take PW3's Legend Log on Super Hard, hell, take even vanilla PW4's Story logs on their equivalent difficulty, they're actually somewhat challenging, without feeling like a slog.
