What I truly hope for won't happen because I think I have a pretty good understanding of what direction Larian wants to take this game.
That being said, I'd like:
Paladins, warts and all. Considering they are a very popular class, I suspect Larian is trying to figure out how to implement smites, which are kind of like reactions, which is causing the delays. I say bring them out so I can at least know exactly what to expect.
Level 5. Highly doubtful but this is a wish thread.
I had a convo a while back about reactions and Paladin's Smite. In 3.5 smite was just a ability like sneak attack, which caused confusion in the convo with myself not knowing it got turned into a reaction. If they go forward with current reactions, Larian could go the route of Smite going back to 3.5.
