Would it be better if this product was an LCG? Yes.
Would it have been confusing having two different SW LCGs? Yes
Would it have been hard to market LCG packs that included tons of dice and therefore been more expensive? Yes
Would it have been impossible to sell an LCG product with tons of SKUs in mass market stores? Yes
There's tons of legitimate reasons why this game is collectible - it's just different - it doesn't mean that we should wish for it to be a flop
