Had to do the same thing but had a different experience. It was hard to dive in and took some time but now I understand and appreciate the core concepts. There are many abstraction layers ("[...] schemes") and IMO that is a good thing. When you customize workflows etc. you can do that without leaving supported areas. Creating and changing a workflow is very easy. Plus, JIRA has a good pricing. With ~350 employees and many mixed teams using only Trello would be chaos. In key areas we need fixed workflows (-> JIRA). Right now we are planning to add Wekan (FOSS trello clone) to our toolchain for workflows which are more dynamic (less "C follows B follow A" + smaller teams - e.g. innovation and some planning).
