Perfectly honest feedback: hate the clickbait titles/descriptions, and took far too long to get to the point. As for the advice of not lifting shuttles off serve for beginner/intermediates...well it applies more to intermediates as beginners can gain plenty advantage lifting it to other beginners/beginner-intermediates who don't have many options in the deep rearcourt. At this level, it's often the side that has the stronger retrieval/defence/counterattack that wins the games, not the side with the strongest attack/smash. It's a bit like people advising not to high serve in MS, because all the pro's do short serves. Yes, at national level, MS players have 350kph+ jump smashes off high serves that even a dive defence can't cover, but at a beginner/intermediate/high intermediate level, we certainly don't, so a high serve is actually very effective anywhere but the highest level of MS competition. For doubles, lifting off serve is probably perfectly fine until you get to relatively advanced play - regional level or higher. Obviously if you aspire to play at such a level, it's essential to learn it sooner than later...but it's not the only winning strategy in lower level play.
