Aside from the copious amount of helpful detail and insight (especially for being relatively newer to the scene), that was just a great read altogether; I've peeked at the other stuff on your blog and enjoyed the rest too, you're a wonderful written voice.
I don't have a great deal of new input, since the time I took Hunt far more seriously was mostly before people (Jean) really started try-harding, but I've been sitting on the thought for a bit now that singleplayer speedrunning ability plays in more than I originally thought. Tactically, Hunt is obviously a way different beast, but I've been impressed with myself at how well I still navigate the older maps and how quickly I pick up on the newer ones because my basics are still fantastic. There's definitely a parallel to this idea to a football player dribbling through cones (or any other equivalent in sports). So while I'm not saying specifically to play singleplayer to improve in Hunt, it's probably a good alternative to solo hunt play if you need the change of scenery.
Thanks for the time you spent writing this.
