The game is very good, but I'm playing on tactician and I never feel challenged in battle. It's a bummer, as fights are a big part of the game and they become repetitive and dull because of that. My characters are never in real danger I never need to reload a save or use the countless potions or arrows I stored... I totally understand that the game can be difficult for some less hardcore players, but experienced players who like to min/max are a part of the public. And it's sad there is not a difficulty mode to challenge them.
Reworking the XP curve could be the easier way to make it. Currently if you do the sidequests, you level up quite fast, you are overpowered mid-game and you are locked on the level cap in all the end-game. I guess the fights I found too easy mid-game could be more difficult if I had a few less levels. I'm looking for mods to change that, but it would be nice to have it in the vanilla game.
Gold is also an issue. It's a pleasant feeling in RPGs to meet traders with powerful items you can't afford yet, it gives you a motivation to progress and get more gold. Here, you always have waaaay more gold that you need, it feels pointless.
