Well the problem is that there is quite big inbalence in equipment.
Not really. Some of the boni on equipment is pretty useless for some builds, but that is about it. Not really a problem.
For example for all cloaks characters need intelegence, which is totally useless for non-mage character.
Raise the Intelligence of your fighters/rangers. With 7 intelligence (I believe it was 7) your character can wear every cloak in the game. Might be a strange design decision, but I guess Larian thought it would be a good way to nerf ranger/fighter builds a bit.
Or random stats on metal bracelets are for ranger, with requirement of 8+ strength, which is useless for ranger.
Rangers use leather bracers with a high dexterity requirement. Metal bracers are for fighter classes.
