Still figuring out how this class works and haven't fought beside enough of them to know the many various forms and their strengths/weaknesses...

Do you only get one form at each tier, for each of your major and minor focus areas? Is that form determined randomly? If not, what matters?

Any tips on how to place this class well, or special things to do (or not do) while young that will make a more effective character down the road?

Thanks for your help!
