Yeah I guess to cover all bases the better option that doesn't gear us at an unacceptable rate would be the option to Veto 1 of the loots for a re-roll. It just seems a bit lame to me, no immersion behind it if you know what I mean, just yet another UI window to mess with. Lot of people mentioning they'd like a system that recognizes the classes and specs of group members. The problem with this is that blizzard only want us to gear at a particular rate, so a system like that would too drastically increase gearing speed... there still needs to be SOME wasted loot, just not as much as currently.
Useful loot always drops? Sweet. Oh, now we're full bis geared. Blizz make maor content plz. < Every time something like this comes up, this is the situation blizzard sees. Is it somewhat silly that RNG is, to a degree, necessary to prolong the life of the content? Yeah. But it helps buy development time.
