For 7. I think it's a very good thing in a an RPG to be able to do that.
If you can defeat enemies through great skill and knowledge, it rewards the players who engage with mechanics and learn attack patterns, if you can defeat an enemy by grinding for hours and then steamrolling it, it rewards players who spent the time to farm in order to ease them if they lack skills. Both are good.
Although i hope that have maxed up sexual XP won't make the game near-impossible, softlocking players is never very fun.
