I'm not sure of the history of FFGs game balancing. But may I suggest that fixing a card by introducing another creates giant swings which do more to make an unbalanced game even more unbalanced. Sooner than later the game revolves around one card.
Issue #2 Unfortunately there are certain unbalances already in existence. I was hoping that Corps would get a 'buff' in the last data pack but I'm afraid Oversight AI is far from it. Becuase oversight AI requires a click to to have first installed the ICE and again another click to rez it, I'm not confident its slowing the Runner down enough. … its bad enough that the ICE is trashed after it's passed through but now its double bad becuase of the click to play it's operation cost.
I'm not so sure theres a single card thats making the Runner so much stronger but really the combination of cards and there speed. Versus how slow the Corps has to be. I believe the win rate for Runners is about 60% from the current data; that's fairly signifcant.
I'll keep a close eye on how this imbalance swings in the time to come.
**Also note; the game is brilliant when all the factions have the same chances to win/lose. But it will lose some of its flavour if one faction is clearly dominating (similar to HB / Criminal / Noise) who get a majority of play. I realize each faction has its own style and will appeal to certain players.
