I usually just haunt the forums, but I think this MAJOR distinction between 4e and 5e can't be forgotten
In 4e, biowire was insane because TMs could thread skillsofts at, really, whatever rating they wanted. Since biowire had little to no limitations, this a rules-lawyer could be allowed some frankly stupid builds that every sane/experienced GM canned instantly.
That's not a a problem with this as you CANNOT emulate skillsofts in any way as a TM. Its impossible, barring some VERY loose interpretations of the [program] echo, and, even then, you could NEVER change anything about it. Purchased skillsofts have a hard rating limit of 6.
This means that, while overclocking DOES let you run alot MORE skillsofts, potentially even up to the max rating of 6 with a rating 6 skilljack and enough nuyen spent on skillsofts to sink a ship, it CANNOT let you exceed the max skillsoft cap of 6 as those are not a part of the cyberware.
There is no getting around this limitation, so you do not need to worry about the old 4e nonsense. This, at best, saves them some essence when it comes to skillwire builds in exchange for a sustaining penalty or 2 to all actions. Can be nice, but far from gamebreaking.
