Yes, there a few things to consider here. A: The game is in Early Access, and Larian is tracking things like when characters and parties die. B: As stated, this game isn't like Skyrim, where you can solo every enemy on the map. There's a reason why you have a 4 person party. That's where the strategy comes in. Take your time. You don't need to rush through anything. This is just Act 1 and there won't be another for a long time. C: Get used to the mechanics and know your character's abilities. They are made to complement each other.

All in all, take your time, LOOK at everything. As you move, pay attention to aspects and parts of the map that might conceal an enemy or a trap, but yes, traps exist because your enemies are a-holes. :P
