Hello and thank you for your comment with so many suggestions, but some of them go against core design of the game.
Souls-like games are more of a RPG and don’t follow rogue-like pattern of giving different opportunities each run. For rogue-lite/like game it is important to provide small decisions that will add-up in long run. Hoarding stat points doesn’t fit that.
Pokémon series at core designed around idea that Pokémons are expendable. Loosing one of them doesn’t mean you loose match and loosing a match doesn’t mean it’s game over. Because of that Pokemon system can allow way more extreme balance, that doesn’t fit for game where one damage can be difference between win and game over.
“Paper Mario: The Thousand-Year Door” system may fit if adjusted, but it would be closer to normal RPG experience system, providing points for leveling up.
As for everything else: New enemies are planned (ofk they are not just reskins of same enemy), new characters are planned. Potions and stats will be rebalanced in next update.
