*MF swapping made obsolete. Your MF rises 'slowly' to its max equipped value ie over ~120 seconds from you equipping a piece, its MF bonus is added to your character sheet - cant swap just before final blow, unless you want to kite around last mob for 120 secs.
*Levels of Excellence added. Gain a temporary 'level of excellence' on each elite kill. This number is tracked on your character perpetualy and you dont lose it if you change games/acts etc.
*Every time you kill your 500th elite, a guranteed Legendary drops (ilvl and affix rolls depending on Act and MF Gear as usual). This resets your 'Level of Excellence' to zero.
*This Legendary is BindOnEquip, so now while a certain amount of farming gurantees everyone a legendary drop, you need to make a choice - use it/save it for alt OR put it on AH/Trade. Cant use and pass on. This will provide the much needed item sink, else a guranteed Legendary drop will eventually flood the economy.
*This LoE system was favored for its simplicity and effectiveness. Its pretty much the WoW 'token' system, which essentially gurantees end game gear progression, as long as youre running the content, even if youre missing out on drops.
*Theyve spend a lot of time and effort making Legendaries cool. Needed to strike a balance between them being too common and too rare. Hence this system, as well as making them BoE, to ensure balance of economy.
There will be some changes to affix rolls of class specific items
