just a little on "respecing". The allow you to do this in D&D Adventure League as many times as you want before level 4. The first thing you do at level 5 solidifies your choices. The only thing you have to do is ensure you're starting items are returned if you change backgrounds.

This can be abused, allowing for "min-maxing" of tier 1 content. Essentially you can just have a setup that is efficient and then do some crazy modules with fat loot, then at level 5 you setup your forever build with the sweet items you cherry picked content for. In this game, the content will be static and the same every time, so its arguable if respec may actually be a nice thing.... knowing that your companions may leave you based on your decisions you may want to change your class after the first act. All they really need to do is put in a nice system for hiring generic companions like ing DOS2 (lizard lady on the boat after the first act). With the option to hire mercenaries, you could just replace whatever roles you lose to choices (if you side with the Gobbos)
