1. The game starts out with really challenging combat, but as the game progresses it becomes easier and easier to the point that everything is just a cakewalk.
With fairness though, this is pretty much every RPG ever. The genre is notorious for an inverted difficulty curve and the power creep that comes with progression mechanics.
Even Tactician mode in the OS:EE became a cakewalk once you passed a certain threshold of acquired skills and experience using them.
That said, it depends heavily on your party mix, and when you take on certain challenges. Ive started this game now with several characters/party mixes, and I've struggled with some even with superior gear, and blown through the early game in simple rags with others. All characters can become powerful, but they don't all start out that way.
