Robes = Mystics classes (Nukers, Healers/Buffers/Summoners)
Light Armor = Damage Dealers (Daggers, Archers, Summoners, Warriors)
Heavy Armor = Tanks (Knights, Warriors)
For the most part, anyone can wear anything. You just won't get the benefit of armor masteries of that type. (ie. If you have light armor mastery you get added pdef, that a person who does not have a mastery will not get.)
There is also 10 point (base) difference in evasion for melee classes between light and heavy armor. For the most part this is inconsequential until the evasion passive skills start to add up later. (If your class gets them.)
For Mystics, things are slightly different. All mystics have a set of level 1 (base) passive skills that increase MP regen, and attack/casting speed in Robes. For later class changes that do not get masteries in Light or Heavy, wearing anything but robes has some noticable downsides. For classes that do get the masteries there is still some minor MP regen/cast speed differences, but they are much lower than if the character had none.
Mystics by armor masteries:
Heavy/Light/Robe: All Orc Mystics, Prophets
Light/Robe: Bishop, LE and DE summoners
Robe: All Nukers (This includes the Necromancer!)
For all melee classes, Heavy armor tends to outperform light armor even with masteries until well into second class change. Thus many daggers forgoe using light armor, sticking with heavy despite a lack of masteries until at least L40 or closer to L52. Many archers like to level up with a dagger for the similar reasons/levels.
