I find the rest of Trailblazer a bit over-engineered and prescriptive, but I really like cells (http://trailblazer.to/gems/cells/ http://trailblazer.to/gems/cells/). IMO these are good for encapsulating view state. It more replaces the "helper" layer than controller layer, but it also helps you write controllers that just focus on HTTP stuff and nothing else (together with service objects, of course).
