I am not exaggerating when I say that when I saw the changes in the test server, my heart sank. I enjoy this game, but I find it a struggle to progress. Since the changes with the combat system I lose more than I win and the only way to make any difference at all is to buy Boosters - this usually takes up all my kobans each day, meaning that by the end of the day I usually don't even have enough to spend 12 to fight all 15 tower fights or collect all the earnings, and going through one by one is tedious and time consuming. So seeing the new booster line-up where the cheapest booster I've seen is 90 kobans to fill just one slot and the likelihood is that you'll need these 500+ boosters (which I cant afford) to stand any chance, I just can't see how I can keep going. I can't afford to spend real money on the game and its one thing to grind, but when you try and grind but get nowhere (or in the case of seasons, actually go backwards), then the game stops being fun and you realise it's probably time to give it up.
