Huh. I like both games so far. I don't quite understand why you all hate Pathfinder so much.
For me, it's Owlcat's quantity over quality approach, at least for WOTR (didn't play KM).
Big thing - crusade, for example. It's an unbalanced, watered down HOMM that's mostly disconnected from your traditional party adventures. Yes, you can set it to auto - but in that state it can screw up some of your mythic-related quests for some paths. And if it can be auto'd - what was the point of making it the way it is in the first place?
Classes and subclasses - yes, there are a lot but what's the point if it starts lessening the choice when you understand that any more of less serious enemies will have inflated AC and are capable of one-shotting or nearly one-shotting you. So even if you're not minmaxing there's a major incentice to optimize, hence lessening the choice. Or you want to play a blaster caster? Well, good luck, most of the demons have resitances to elements; worse if you want lightning as there'll be outright immunity, and you can't bypass these until the end of Act 1 for your chosen element. And on that side - I'm going through act 2 (second-ish playthrough) and it's insane how stronger a fully-buffed party is compared to an unbuffed one. And with Enduring Spells mythic line it becomes a play on how many buffs you can stack for 24 hour duration. Mythic paths - while any class can choose any there are still very clear synergies for some, especially for paths that can merge spellbooks. Essentially, the game GIVES you options but EXPECTS you to play in a specific way.
TB vs RTWP. TB slows down the game to a crawl... and the game was made with RTWP in mind so it should be better? Well, personally, I find WOTR RTWP hectic, especially if you want to actively use offensive spells due to how much can be happening on screen most of the time.
I do like the story and characters though, and that's pretty much the only thing that still keeps me in the game. Hopefully I won't burn out this time...
