As mentioned above, nothing has changed about how we would interact with sp1 or sp2 normally. They just updated the text to more accurately describe the phenomenon. So @Woody141082 yes, we interact with spidey and km the usual way.
Sorry, but it has not always been the way it is now. I have taken path 6 in war for some time now which begins with an SP1 node. There is a difference in the way it interacts as I experienced just last week. Before, I was not able to block Iceman's special 1 whereas I did just last night. I thought it was a bug last week when it happened with War Machine and I was able to block it, thus prompting me to reread the node and post this. If you guys have not experienced a change then there must be a glitch. That would not be surprising with all that has gone on this month.
