So now that I'm learning a bit more about PoE and the basics, I've started my third game now and bumped the difficulty up to hard. Realizing I never got much farther than the stronghold portion, I'm reserving future judgement on how difficult the game will get (though Normal seems too easy for what I'm looking for).
My question, now, is (at the stage of game I'm playing) how detrimental will it be that I'm not using a perfect build for my character? For roleplay reasons, I haven't spec'ed my built for optimization entirely (16, 8, 15,14, 14, 13) as a rogue, but I'm planning on taking a full 6-man party. None of the characters will be re-trained because, for my strictly RP playthroughs, I feel that controlling the progression of other party-members so much is almost like power-gaming (though I have no issue doing this on subsequent playthroughs).
Using an RP-friendly build, with RP-centric party-members, will Hard give me much trouble during the entire play's lifespan? Or is this game like IWD where you're almost expected to power-game to a certain degree?
