As someone who has played DMC and Souls series, am I that crazy to find the W3 combat fun? I get that it isn't as good as those but it doesn't need to be.
Nah. For ARPG combat, The Witcher 3 is better than most of the non-shooters, but less good than Monster Hunter, Ys, Soulsborne, and Dogma (the Japanese heavy hitters). Maybe better than Kingdom Hearts although that's contentious: to some, KH2 Proud Mode lvl 1 is the best "character action game" ever made. Diablo has its die-hards as well. If counting shooters, I'd still put it lower than Fallout 4 and Mass Effect 2 and 3.
I think it's a fine and completely acceptable departure from hardcore combat engines like DMC (my favorite), even if it is janky. Obviously it could stand improvement, but the genre as a whole could. Not that it's a priority (unfortunately?), because Skyrim/Fallout/Witcher sell a ton more than the others.
Is this the part where Dragon's Dogma, Souls and Monster Hunter don't count because reasons?
This is a strange point all around. WRPGs made their impact on the original Xbox with KotOR and the like, which were turn-based or real-time with pause; before consoles, WRPGs were known commonly as CRPGs, or Computer RPGs. The RPG genre as a whole turned more towards action-based combat engines, which meant Western Role-Playing Games suddenly had a genre shift and soon became (incorrectly, imo) associated with real-time, action-based combat while Japanese Role-Playing Games were commonly known as the turn-based affair commonly found on everything from the NES to the PS360 (a gameplay style used for nearly 20 years). I'm sure he meant Final Fantasy/SMT/Costume Quest likes.
The entire reason action-based combat became popular was because the market responded better to it than turn-based combat.
WRPGs saw KotOR, Jade Empire, and Morrowind (a hybrid), and then Oblivion, Fallout 3, Mass Effect and Dragon Age (a hybrid on consoles) soon after. Western ARPGs weren't called WRPGs before KotOR: Champions of Norrath and Baldur's Gate: Dark Alliance and etc; before that, Western RPGs released on consoles were (correctly, imo) called ARPGs, or Diablo-likes. The point here is that WRPG was originally coined to distinguish the western-styled turn-based gameplay (in KotOR and commonly found in CRPGs, and even still in games like Divinity: Original Sin) from the Japanese-styled turn-based gameplay (found in Final Fantasy, Dragon Quest, Breath of Fire, Persona, etc; and, even in western games like Costume Quest, Child of Light, and Anachronax).
The way discourse has evolved has everything muddled. You've got people comparing turn-based to action and action to turn-based: "Divinity shits all over Soulsborne!" "Soulsbourne shits all over Witcher!" "Witcher shits all over Persona!" "FFTactics and Disgaea shit over them all!" "I like Mass Effect!"
IMO, the splits should be: JRPG, WRPG/CRPG, SRPG, and ARPG.
ARPG of course includes everything from Ys to Soulsborne, Dogma to Witcher, Skyrim to Mass Effect, and Deus Ex to Kingdom Hearts.
Apologies for waxing rhetoric over your fair rebuttal. The convo just annoys me because there's no consistency between arguing parties.
