Gloomhaven Summoner Strategy and Preferences - The YOLO Summoner??

I had a great time playing the summoner, but I ended up having such a good time by doing some things that I don't think are the norm. Is it actually viable to be the one leaping in headfirst into full rooms of enemies? Surprisingly, I think so! (eventually - the early couple levels not so much). Anyway, since I had such a good time with it, I wanted to share some of my thoughts, strategies, tips, and tricks. I can only assume this isn't the "meta". This all said, the Mindthief is still my favorite.
