Blizzard's plans to introduce reforging in Cataclysm are a welcome change for high level items, as in principle they mean that more gear can be used, rather than disenchanted.
The trouble is, reforging applies only to high level items (I think the lower limit is iLevel 200 in the Beta at present), which leaves a whole bunch of stuff (e.g. in Outland) which was designed for the old stat weightings (e.g. spirit being useful for mages) that is now useless.
It's hard to see what the benefits of this lower limit on reforging are. As things stand, many formerly useful quest rewards are now just vendor trash. Of course this could be resolved by re-working all the items in Outland and Northrend, but wouldn't it just be easier to remove the lower limit on reforging?
