Very nice thoughts and most of the comments after that are not at the same level. They seem to come from people who never thought a bit to the balance in DD5 rules. Presently, the issue with advantage / disadvantage as well as the number of HP of some monsters that have been artificially increased breaks many aspects of the game. Many competences (and the full rogue class) and spells become useless. Solving these issues would re-equilibrate the whole game and give a richer gameplay, since some spells as support spells would become useful again.
