A list of successful spy paths that end in stabs that you could iterate through would be pretty fascinating. I guess the list would be a bunch of "heat" paths, pooled together somewhat, ordered most common to least common. You could also have a sibling "heat" path that started in a similar place, and ended in a similar place, but ultimately resulted in a death.
Yeesh, there's tons of things you could do with heat maps that would be amazing.
Some of these ideas might require additional server plugins to be created though.
Few things I noticed:
-The badwater 1st cliff spot isn't even green
-Steel E Offense Sentry is hotter than Defense spot
-Sentry in connector (Viaduct) viable?
These heat maps are absurdly old. I recall when badwater first came out, everyone was building sentries inside that shack looking straight at the first cap point. I imagine if they were redone today, you'd see a ton of placement on the cliff. But yeah, this is all from a pub server.
