I personally don't want them to implement it ever, it's not like you don't have time to research and judge accordingly to what you may want if it's a question of mark items, the quest where they have you choose runs you to all three. instead of blowing through it with no regard, try looking at the list of items, seeing what appeals to you and choose that way, or if you've got a bunch of friends/LS mates in different ones, ask "what made you pick choice A, B or C". You SHOULD only be able to choose once, it's not retail where you can just return it if you don't like it, so pick wisely. I do like the idea of being able to cross buy between companies, for a little extra on marks...like 15% sounds good.
