Week ago I was trading with my pal and he pointed out that he values x1 cards from chapter pack a little more than those x3. He said "something like rare".
Now two thougths:
1) Sometimes you don't remember which card was x3 in pack and you don't know if you want to trade for other card (quantity of which of course you also don't remember). Solution to this (as you don't have internet access all the time) would be a number or a little dot next to card's collector info. For example:
F1 34 and F3 25.
Or
F* 34 and F 25.
Or something different that allows you to tell quantity. This is no big problem, but if FFG could do it without big work, then it would be nice.
2) I'm so glad with "Princes of the sun" that I thought: wouldn't be great if chapter packs was all x2? You could split it with friends without problems and easily collect playset. What do you think guys? Would it be better/worse for players? Would it be better/worse for FFG? After all it shouldn't be rarity in LCG
