I'd argue that they should add more variety with armor designs and color variants without too much stat boosting before we reach Act 2.
With BG3, the characters are low level, hanging out in the middle of nowhere after a crash, and they can already get their hands on dozens of magic items, including multiple instances of many weapon types. It's almost too much already if you ask me.
You said it perfectly.
Warped Headband of Intellect is the perfect example of being too much for early access.
I agree with Maze comment. I just want to chip in my opinion on the headband of intellect here... It *looks* awesome the first time you find it, but its use case is really quite limited. A wizard is going to be pushing int anyway, so the headband just gives it to them a level early (if you get it at 3). After the wizard reaches 18 naturally through ASI the headband goes in the trash (or to another character as a buff to int skills, which is hardly broken).
It might get more mileage on an EK, but even there once you hit level 5 you will do more damage just attacking. Its a buff, but I do not think it is enough of a buff right now to overcome the advantage of the battlemaster over the EK.
In other words... the only time it is useful at all is at low levels, and that is exactly when we get it.
If they add the attunement mechanic from 5E then it will get discarded by even the EK as soon as they find three attunements that are better.
I am plenty willing to criticize Larian's approach to BG3 (and have done so in other threads) but I think that the intellect headband is very well placed, and should not be removed, or placed later in game. (In DMG it is listed as an "uncommon item" which means that it can show up in treasures appropriate for 1rst level or higher).
