I disagree.
You think there is too many encounters ? Well, to me there isn't enough encounters, especially in the Phantom Forest. Battles are what thrill me the most. Reading endless dialogs and roundtrips to complete tasks is not what I enjoy the most in a tactic-RPG game.
I agree though that the game gets too easy after Cyseal. Once you get Master skills there is no more challenge. There is a serious trouble with balance, as I always overleveled the content past Hiberheim. Fighting some 16 orcs when you are 18 is not fun in any way.
The game would benefit some level buffs for foes.
