this reflects my team's experience, initially skilled programmers (from C# mainly) complains almost hourly about lack of IDE features, in particular - Debugging. 14 months in now with 9 major services in production, I hear no more conversation on this, and still no one yet bothered to setup dlv. 'Breakpoints', to our surprises, is not actually indispensable. Also I noticed positive cultural change around, we move faster and team talks about business problem solving more than programming itself, to a point I believe rich functionality IDE over complicated things we do here.
