MortalKombat33: That's the problem with game balancing, particulary, with how higher difficulty works. Since "difficulty" is the highest at early stages (on higher difficulty settings), your main goal is to break through early stages, even at the cost of weaker power later, since your power in late-game would be enough anyway. At higher levels, some "dips" arent really neccessary. AC from monk? You can get enough AC even without that! Mirror image? Just equip a certain amulet. Etc.
That's a good point about the difficulty trajectory. And I agree, it's hard to balance something like this. There are always people who break the game via all the permutations in builds in a system like this, so then the developers have a hard choice. Do they balance for the more regular players, or the more hard-core? Overall I'm glad they did as they did, because there sure are enough games out there that can be played almost on auto pilot. But it does have the consequence that either you go for the same min-maxed builds that all the guides talk about, or you play on a lower difficulty setting. Normal should be fine after all, and was fun on my first and blind playthrough. Going higher than that..? At least challenging seems to be fine from level 5-6. Maybe Hard too, or with a few more levels. At least if you have a proper tank with sky-high AC.
MortalKombat33: As i said, most (if not all) your companions have shit builds, often - beyond any help. A deadweight, really. Naturally, playing higher difficulties with a deadweight is a nightmare. IDK, what story designers were doing, really. They basically leave us no other options that use mercs or even playing solo. I play solo character on "hard", and i bet, it's much easier, than playing "challenging" as with 6-man party, where 5 are deadweights like Harrim.
Many of them seem fine to be to be honest, and I don't get all the complaints about Valerie. Harrim, however, is utterly useless. Maybe they wanted him to fill a different role than Tristian. But if they kinda wanted Harrim as a battle cleric, then he needs AC. Right now he seems pointless to include because he can't do anything well enough, even for Normal tbh.
Haven't used all of them enough in the campaign yet, but what I do like about them is that they are well-written into the story and have a personality. Harrim is pretty terrible even there, but at least he does fit with that depressive god of his. Overall I think Owlcat did a good job actually, as there is no need for super min-maxed companions in a role playing game. It makes things more difficult, certainly, and I'm kinda arguing against my point from earlier, but compared with BG for example, which had many fairly terrible companions stat-wise, this game is better in that regard.
Also good point about solo (if one can survive the early levels), as you presumably gain XP very fast, while as a full group it's a slow process, which means we can't reliably hit level 20 by the end of the game. Solo with all XP for themselves probably get there by mid-game or something?
