RIP. Classic hammerdonks are always fun
Couple of advice if you want them:
You should treat classic hammerdonks more like a sorc. As in, stop worrying about your defense too much. Its helpful yes, but + life and + res is waaay more important.
As some1 already said, Ornate dins are only viable when you have a -30% req ornate plate. Otherwise its just waaaay to much strength you need to put.
That being said, mage plates are your go to armors and its a good idea to imbue them. ^^ %ed for a hammerdin is like your 3rd most important roll. After +life and +res.
With this in mind, 3 pdiamond shield > 2pdiamond shields. forget 2 sox.
This is based on my experience but ofc, if you think you need + def by all means do it.
