Itemization in the game is highly variable.
Some items are extremely cool and well designed. I was worried a lot during EA but I have to admit that I really love what Larian did with some items.
On the other hand, 90% of them are totally useless or highly specific and it apply to legendary weapons too.
They are usually good but I agree with Ragna : it lack variety and some classes (or build) don't even have a very good weapon at the end of the game (or use the same again and again).
Only 1 staff, 1 * 2 handed weapon, 2 great finesse weapons but you get them at the very end...
Other weapons are very specific like Nurylna that is only great for thrower build, Duellist prerogative that has very cool passives but require to have an empty hand, Shar's spear really sucks, the mace is okay but not so great in act 3 both for martial or caster cleric,...
I really wish the definitive edition will rework most items in the game. I'm sure Larian know we are always using the same 10% of them^^
