@Zerosum.
I read your houserule in the other thread, I found it easy, sleek and intuitive.
And I guess technically you didnt houserule IC, but more just hosts loosing the +1, +2 and +3.
What I really like about that rule is, if your game suddenly became more matrix focused, it would be easy to just introduce a host with rating x i everything, but x+2 in attack for instance
Personally I would still go with the various bonusses, as per upcoming errata. ( not that my games have been very matrix focused so far :/)
