Diablo III: Reaper of Souls

Useless? Correct me if I'm wrong, but legacy items are what people will be using for the first few levels on their way to 70, as I'm sure that while post-Loot 2.0 60-63 items will be a bit better than what are dropping now, if you have current end-game gear, then you won't be switching to post-patch gear so quickly.

Any pre-59 Legacy item is useless. Most level 60 Legacy items are already useless as they are. Any level 60 Legacy item that is currently useful is useful until you roll something 61+ for that slot. Given how retardedly high the stats roll in Loot 2.0 (look at the level 60 Echoing Fury in the article), it won't take long to replace all your gear.

The only reason to buy Legacy gear right now is if you still intend to play regularly up until the patch, or it's an item that would upgrade you post-patch with an enchant and you're too poor to afford it now. Maybe they'll have a price spike just before the patch when people realise they could get a cheap upgrade to farm Loot 2.0 with. The pre-expansion patch will probably last a month or two, giving a ton of time to outgrow your current Legacy gear.

If Blizzard plans to implement a ladder too, the majority of players will migrate there, leaving the current non-ladder characters' gear useless for the most part too. It'll probably take a day or two to get some decent rolls out of Loot 2.0 if you're dirt poor. If your gear is rich as pineapple already, it'll take a bit longer and that's where enchanting would come in, to increase the life of

For example, I just bought some 200 mainstat 12% HP 9 IAS Mempos because I can't be asked to buy a crit memo as they're currently priced.
