It's really obvious how much high ground dominates combat. I don't understand why they have released the EA like that in the first place and refused to tweak it for 5 big patches.
The Zhent Hideout is probably the most glaring example. Push the boss lady and her sidekick down and kill everything with ranged weapons without ever getting hit. You're in their base and there's a lot of Zhents there. It's supposed to be dangerous.
The huge advantage/disadvantage swing is the biggest offender but also being able to use Thunderwave or Pushing Attack AND Shove on the SAME turn... what were they thinking? And are still thinking?
