Hell no. A +1 stat guarantee would make the game too easy. In my experience monster battles are like 60% of my encounters, regardless of build.
I feel like lewd degree in general is much easier to raise than the other combat stats. You can it consistently from many different sources, like failing to steal from a tent, asking the right monk the right questions, sucking the library dude off, public masturbation at the inn, and seducing the bridge guy. The not-so-consistent sources include meeting a dude in the desert and stealing from the dude with a cart. If I just wanted to raise strength or leg strength, I maybe have like the person who raises 1 stat of your choice, investing in some dude's shop, and maybe the Library, if you're going for magic. Otherwise, you either get a random stat up from fights or other sources or an event that has a chance of failing and hurting you, like walking through the woods or river. And this isn't even counting the fact that you can get double the lewd degree gains with the right starting buff. What they actually need is to make the support cards more convenient to use or powerful. Otherwise, they're just too situational compared to Lewd decks. With a lewd deck, you can indefinitely stall monsters and sit on passive healing.
