(Assuming you do this professionally) that doesn't sound great for the make up of your team.
I think I like bug fixing/performance fixing/'design' (as in db, infrastructure, code structure, refactoring - not UI) most. I don't mind new feature work, mainly because it typically involves some if the latter I suppose. I really don't like total greenfield work though, where you have to faff about with all the initial config of stuff (which assuming you don't start a new project every day you haven't done for ages) - especially anything to do with JS where you also have to work out how to do it without their 'helpful' cli tool, or how to combine a slightly different 19 tools & frameworks than the example you found.
I also enjoy the detective work, especially for performance issues. I find I don’t like actually addressing the problems once I solve the mystery, however…
