Warcraft 3 is the only non-WoW game in the saga i've played and while I enjoyed it I thought Starcraft 2 was better. (which should be getting another expansion sometime in the next 10 years) But I dont think you'll get a Warcraft 4 for the same reason we'll never get a Half-Life 3. MOBAs and e-sports are too damn popular/profitable.
The boss that gave me the most grief was the Loran Darkbeast. The boss itself was pretty tough but the framerate made it maddening. I'm working on beating Amygdala in the cursed chalice but none of my weapons have the reach to reliably hit that thing, beating it in the main game was hard enough but with half health it requires a lot of patience.
I really like the chalice dungeons though, it's a nice refresher between NG+'s.
I prefer playing as Kung Jin in versus but i've probably spent more time playing as Takeda offline. Personality wise I like Cassie Cage though.
I think Erron Black's character design is very uninspired. I know MK has always had pretty basic looking characters and that's part of the appeal but I wish they went a little further to go beyond 'outlaw cowboy' and 'aztec warrior' Ferra/Torr is pretty original though. Shame I cant stand how he/she plays.
People know, it's just laughably bad so noone talks about it.
Honestly I think it's kind of ridiculous you cant do ranked matches while working your way up the ladder like you can in DOA5 & SF4. Also, I could be wrong (maby I havent done enough or maby it isnt working) but are ranked matches even ranked?
I like MKX but I feel like they messed up the online pretty badly.
