There are issues with the corp being able to keep up with the runner. Particularly post-rotation (read: post-Jackson), it seems like there will be some issues. Ideas have been floated about this.
Also, when there are new cards released there are always loads of awesome-looking corp cards that can never find deck space because so many cards are already required. Once you have your agendas, economy, and ice, you have a limited number of slots.
I was just thinking, what if the deck size limits were increased a little bit? For example, on 20-21 agenda points what if your deck size was 45-52 instead of 45-49? It's just a few more cards, but it would cut agenda density down a little. You could have three more ice or econ or what have you.
I'm pretty much just spitballing here. It seems like a pretty simple balance fix though. Thoughts?
