Personally I don’t think Netrunner needs much in the way of immediate balancing, and that the natural evolution the card pool will likely be enough to keep the game from becoming stagnant or overly dominated by any particular deck archetype. I’m adverse to the idea of errata for power balancing, and banned/restricted lists seem equally inelegant.
It might be interesting, however, to think about game balancing through editing the rules.
What if the timing structure of a run was changed? What is certain effects that currently stack, were made not to stack? What if paid ability windows were added or taken away? What if the conditions under which the corp could rez ice were expanded? Those kind of things.
There’s a lot of complexity in the rules of Netrunner - are there any surgical edits or wholesale changes to the rules of how the game is played that could lead to a more interesting or more balanced game?
