I only ever played at an official GW store a couple of times when I was younger, and I hated it. The rules lawyering and WYSIWYG nitpicking drove me crazy. Especially since the worst nitpickers for WYSIWYG are always the people with the ugliest paintjobs that just barely meet the requirements for play.
For me as long as it is clear which model represents which character I don’t really care how they look. Especially since I’m all about kitbashing models from different brands, which is a HUGE sin when playing with Games-Workshop tournament mindset people.
