In my opionion the loot is fine as it is. Yes in Inferno we got everything faster, but what came then? Everybody was equipped after 2 month of playing and it became really boring afterwards. I prefer if it takes longer to get the items, even if it takes up to one year for everbody to be equiped.
2 months to get items doesnt mean you finished, what about all the stats? Inferno was insanely bad to get stats, most of the times were cr.ap. This ini seems twice longer and twice worse with this refine system (i still dont see the point of it). Noone will be able to finish the perfect gear in the first year (and im talking about main class, not second or third) unless they add another stats-farm-boss like aldo was and that would make people to not doing the ini exactly like happened in Inferno untill Aldo was nerfed to once per day.
