[OC] An Agile Practitioner's guide to being an unproblematic tactician - Part 1

As a DM or a Player, I find tactician players are awesome. However, they seem to have a bad reputation as disruptive, bossy, no-fun party members. In this video I share why I think they are awesome, and instead of giving advice for how everyone else should deal with them, I try to give tips for how the tacticians themselves can get better at tacticianing.

This is part 1 of a loveletter to my older self, in whom I saw tactician tendencies and may have behaved suboptimally from time to time. But when I recognized a few of these things, I've not had bad table relationships since.

Do you have any thoughts on the topic of tactician type players? Do you think the approach I described would help the problematic tacticians you've encountered before?
