Yeah, I think it's fair to say Conquest on hard is pretty intense. Which is fun most of the time, but occasionally they go too far* and become annoying.
As for level ups, I couldn't even guess at this point. I've died enough times that I had many, many level ups that didn't ultimately count so it's hard to keep track. All I know for sure is that Arthur, true to his bad Luck stat, has had a lot of bad ones. Other than that I assume average overall.
*It's worth noting that as "going too far" goes, this game has not resorted to Awakening's bullshit "spawn a bunch of surprise enemies out of the middle of the map next to your support units" tactics even once. For all of the occasional min-max abuse and unfair level gimmicks Conquest has it keeps enemy spawns completely fair and square, at least so far. I would much rather have this than that, so good. Another way in which this is a superior game to Awakening so far.
