Another option would be to add runesmith like in Torchlight - you could extract a skill/passive from an armour you like and add it to the same kind of amor you like the visuals. But also I would prefer just an upgrade for a cool armor with good skill for a paladin, because there is no good replacement later on, just an armor for a different class.
Right now there are 1, sometimes 2 kind of armors for each class scattered around, but you are not always able to get it, also when you get it is quite too late. Also purple Adamantine forge in Act 1 is quite OP, but you may not like the visuals. But you have to wear it anyway. Atleast it is universal, so you can give it to a companion.
in act 1 - there are 1 kind of class green armors for almost all classes, and quite a lot of weapons, some blue weapons, so master weapon at the end of act 1 is a bit too late.
in act 2 - some green variations, which are useless, because it should be blue
I didn't play act 3 yet
There is some equipment for monks and minstrels, but if I don't play it and there is no companion for it, it is useless even if I would like the visuals.
I really love drow armor with my drow, it does look cool, but I would love to be able to wear all kinds of armors for all races.
