As you know, I go by the words of "Don't play to win, play to improve.". As such, I highly enjoy watching people (who know what they're doing) experiment with builds and show off the ones they find effective without getting fixated on "the meta".
JujuShinobi is one of those players. Not only he keeps coming up with interesting builds for all kinds of 'Mechs, he also plays them really well; leaving you craving to try his builds. He also has a witty and playful personality that makes watching/playing with him a pleasure. Most of his videos are super-close fights rather than outright boring steamrolls.
I highly recommend you to check his videos out. He puts out his videos daily so there's always something to watch.
