Introduction of professions for (Non-combat) XP please. Even finding alternative ways to handle scenarios through dialogue should grant experience.
Wizards should not learn other class spells.
Select best party member to handle conversations built for them (Proficiency and what not).
Dodge Bonus Action.
Otherwise I agree, but I find it curious the see the conversation-suggestion over and over again here. Wouldn't it be weird for you to have a conversation with someone, and when you would wish to threaten the other to get your point across (intimidate) someone else from your party would chip in? I mean, shut up Lae'zel I'm talking here.
It's a party based game and your main character is not supposed to handle all the different skill checks the game has to offer ALL by himself. That's what you have a party for. Every party member with their own strengths and weaknesses, working together to reach a common goal. Therefor, when Lae'zel happens to be the most proficiant member of your party when it comes to intimidating others, she should be the one who makes the roll. If you don't include your party members in conversations, they are nothing more than some hired swords to get the dirty work done in combat and disarm some traps and unlock chests for you. They would lose a lot of their personality that way.
