Sometimes you can select something like "Watch highlights" of a Dota 2 replay.
One day I made a Rampage (killed five people at once) with Techies' Remote Mines, and I thought about watching the replay using the watch highlights function. It showed some boring tower fights—I mean one guy pushing a non defended tower, for example. My Rampage (Pentakill for our LoL players) was not part of it.
How are the highlights selected by Dota 2? Does anybody know this?
