I know that the cardboard tokens are not cheap, ask any wargames designer. But, man, vast quantities of basic opaque dice are ulteacheap if you order, lets say, 500.000 red plus 500.000 green.
In my opinion the basic sets are OK starter kits but to provide only 3+3 dice is one very, very greedy decision. You need at least 4 dice. X firing.at range 1, 4 dice. Tie defending at range 3, four dice.
Please, in future starter boxes, add two more dices. The cost is ridiculous..
