You do understand what a conversation is, yes?Discussing it with an opponent for balance is a TERRIBLE way to set up a game. Why? Because everyone has a different opinion on what is balance. Even non competitive players like to have a little balance.
For example lets take the new 40K Eldar codex. There were people saying it was grossly unbalanced, some said unbalanced but not auto-win, and then you had the ones (often Eldar players) saying it was perfectly balanced. Many of them were not being hostile or rude it was just how they perceived things. Depending on someone's favorite tactics/army their perspective is skewed so what person A thinks is balanced will not equal what person B thinks is balanced. Now without ANY sort of baseline (points/force limits) two players need to reach an agreement on what to play is going to be very hard. Once they finally agree on a game "size" (which now you have no base line for) they have to agree that their two armies are equal in strength, but depending on perspective this could turn a simple trying to have a good game into a balance discussion. If its two people just playing to roll dice and have fun with plastic toys... ok no limits is acceptable, but for any players who want to have fun and play a challenging game where both players feel like they have a chance to win with their tactics... it needs some balance to allow tactics to influence the game.
Sorry to all those Games Workshop fans until death but if this IS the new fantasy game (IE not just the starter rule set). Games Workshop just handed you the laziest rule set ever designed. Writing rules can be a little tough at times (easier now with so many other games to borrow ideas/concepts from), but the real challenge of any game is trying to balance it. A poorly balanced game is a poorly made game. It can have some good concepts, but if the creator leaves out one of the core components of a good game (some level of balance) just because they cannot be bothered with it, its pure laziness. I mean all they needed to do is take what they have written, tested them some, and give them point costs dependent of their performance compared to others and then you would have SOME level of balance. No rule rewrites or another page on the rule book. Just some time and effort...
As someone who plays several game systems the level of excitement over what appears to be a half finished (we hope), or worse half ***ed product is shocking.
