Portal Killer Instinct Range
So Monto is using the Thorny Vines to increase the range that portals can detect people. At 3:55 he charges his ability and his portal is directly next to the door Claudette is near to, she is not detected. At 3:56 after she uses Dead Hard even closer to the portal it finally detects her. Now that range is not far at all and that's WITH an add-on, you can clearly see how close that blood pool is to the portal so I can barely imagine how close it is WITHOUT the add-on because that is NOTHING; the base range needs to be increased and so do the add-ons. In the Stranger Things presentation video it was definitely a suggestion to use the portals as an advanced technique to keep track of Survivors, well advanced players can't get much out of that tiny range so I don't think it's worth saying it is a powerful tool.
Right now it can basically detect someone ON the portal and barely detect anyone nearby and those things make noise so we can't hide them because we have to put them close so that right there means the range needs extending.
I'm tagging @Peanits and hopefully this gets seen because this thread also contains a bug and most of my threads do not get ''seen'' even when I do tag someone but I have to try right. I guess I could tag Janick but he probably has better and nicer things to do than watch everyone complain.
