I just like to praise this game, ever since I've backed it up I've had a great time. It mechanically flawless and to me the best experience from PnP (I've been playing PnP for over 25 years, and this is one of my all time favorites - sorry Torment still #1):
1 - The rule set is accurate to a fault (I very much enjoy the arcana roll to determine a spell before deciding on counterspell or not)
2 - EXCELLENT user interface, I mean, Actions, Reactions, Bonus Actions, Powers, Spells (both as Bonus Actions and regular action), migrating and effect like Hunters Mark, amazing work, very clean, very intuitive.
3 - Monster reaction on Spirit Guardians is AMAZING, trying to move away or not approaching was a very very good, and realistic, reaction.
4 - Spell scribing, crafting etc, again, as the interface intuitive and clean.
5 - Random encounters, not only did I travel far more that I should have, to get those extra random encounters, but when reaching lvl 8+ I started reading the pearl that is "Low lvl Monsters afraid of your party run away". That made me smile.
6 - Quest board, returning to locations with extra quests, monsters and rewards, very cool.
Room for improvement? Sure, but all in all the best DnD experience (5e) I've had outside PnP.
