Number of enemies is fine, but the ease of Long Resting isn't. Resting needs stricter restrictions to be at all a meaningful mechanic. This could be differentiated between Normal / Core Rules difficulty settings so that players who want to keep blasting with reckless abandon can continue to do so, and players who want to play D&D can do so.
Weapon Abilities are not a good design, especially on enemies who will spam all of the same abilities in every encounter. There will be a lot of repetition and frustration.
Giving class ablities like Menacing Attack to goblins should be restricted to bosses like Dror Ragzlin.
The encounter design clearly show us that Larian don't like melee character.
This is a huge flaw and omission in their tactical combat design. There should be choke points and hallways and a chance to matter as a melee warrior. Much more dynamics. Someone over there has a very one track mind what combat should be. Which is jumping around, throwing consumables left and right and abusing the OP Shoving for cheap insta-kills.
