So, maybe I just haven't been playing Netrunner enough, but Wyrm seems... Lacking?
In order to interact with a piece of ice, you need to be of equal strength, correct? It can decrease the strength of ice, but only after matching it's strength, either by paying up, or using Datasucker/Parasite/etc. My biggest concern, it costs 3 credits to break a single subroutine, and only on ice of 0 or less strength. So my question: How does one effectively use Wyrm?
