Dev watercooler - Mist of pandaria looting explained.

Must have missed it, it's up

Ok, after reading through, i noticed a part where it said the new system will only roll for your main spec. Ghostcrawler says the following:
we're not sure fundamentally that Raid Finder is the best avenue for acquiring that loot. You would either need to take it from another player who actually desires it for their main spec, or a conversation would have to take place to make sure nobody else needed it more than you do.

Ok, so there will be no button to press when you win for a need or a greed roll, you will just win.
Now for my idea: When you win, why not let a button show up that says roll for main spec / roll for off spec.

edit oh and before you say: but he also says I've seen some suggestions that we allow an option for essentially "I'm happy to get loot beyond just what my main spec can use," and maybe that's the kind of approach we could take, but let's make sure the basic design works first.

He doesn't specify how you would make that option clear. And really switching 1.kill ->2.decide loot drop ->3.press button ->4.roll to 1.kill ->2.roll ->3.press button ->4.decide loot drop doesn't sound hard.
Maybe the new system is harder to design because they took out the click button part
