There are over 200 cards in your set, no? I create games and highly doubt that any amount of testing of that many cards since the announcement of the game's death has been sufficient. I also know panZ/fanZ devs do little to no play testing, which is why they print so many obvious problem cards.
I understand the amount of time and effort it takes to create something, and that it's close to your heart, but you shouldn't get so defensive over an opinion. The fact is, no matter what philosophy you have on this officially dead game, fanZ is the universally accepted continuation (for better or worse). Trying to force feed your version down people's throats just isn't going to work. (Which you'll argue against, but the defensive behavior and lashing out proves otherwise).
Game balance is hard. And for this game especially, with the almost endless combinations of MPs, masteries, and styles, no set of cards should be released without at least 3 months of internal testing and at least 1 month of semi-open beta testing. (Honestly, it should be 6months total, but for a fan set, I get not taking it THAT seriously). Sadly, the fan/panz team barely tests for even a week (if at all. No way Orange bicycle kick should exist). If someone sees balancing issues with your cards, it's time to take a step back, remove your ego, and assess possible issues. Also, 200+ cards is way too much to try and balance in a game like this in a set with minimal testing. (Minimal as in, the game was announced dead in mid-late January. To create a set of 200+ cards and properly test them in just 2 months with the vast library of cards that currently exist AND achieve balance is just highly unlikely.)
Creating is fine. Posting your creations is fine. Hell, asking people to take a look is fine. But you have to be realistic about your work and expectations of people trying it. As much as you may hate it, fanZ is the "official" continuation of this game. It has communal "credibility" due to the same devs working on it. You're a guy who makes fan cards abd posts them...I'm not belittling you, I'm just letting you know how the community at large perceives this situation. I make dbz cards too, but to expect everyone to move away from the currently progressing game to try out my fan set would just be unrealistic.
Also, you can't say someone who's played the game for literal years actively has a baseless opinion simply because they don't find your cards interesting or balanced. Obvious problem cards are obvious. He's entitled to not liking your creative direction, just like I don't like the creative direction of fan/panZ (it's always been bad design direction with really good mechanics to me).
That said, I wish you luck. Test more and try not to take criticism so harshly.
