I've been trying to work out the number 1 problem with the current structure of d3, its been bugging me no end just trying to nail that one thing. Just like with health issues with people there can be complications but the lead cause is always just one thing. I finally nailed it today, yeah it took this long. Its primary stat for sure. For a long time I've been blaming paragon points since all you need is a tonne of them and all your problems go away but hidden among the paragon levels is our primary stat. Allowing players to gain both offense and defense from one source is the problem. It makes the whole idea of diversity a joke in this game. To make matter worse is the way that damage is calculated so that resistances are really the same as damage reduction. Its just another grouping of damage mitigation. So my point is, for as long as primary stat is so much more valuable than anything else in the game that's all you need. Well that and the most recently buffed 6 piece set.
