Was that meant to be a joke?
Yes... Zenbane was using sarchasm to convey how ridiculous it would be to equal Dark Souls, a praticaly classless game, with PoEt, a game where classes are very differenciated by their base attributes and their complex skillset, instead of a meaningless equipament restriction.
The only thing acomplished by forcibly restricting equipament from the beggining, instead of forcing especialization later in order to be effective, is limiting the players options, in both gameplay and roleplaying.
Why can't my barbarian be a pious prince with knightly training that channels his fanatical fervour into a cold rage as he cuts his foes apart? Why shouldn't a wizard be able to aim straight with a pistol? Why can't my flagellant monk be an avatar of holy retribution wearing armor and crushing skulls with a mace like a templar knight?
Either you code all possibilities that can be imagined within the lore, or let the players build the characters they want and imagine the story behind they. And the first option is almost impossible, unfortunately.
