The one fatal flaw about training with Lichess puzzles - and in general - is that you know that there exists a move that is advantageous toward you, and you have to just find it.
However, in real games, tactics like these aren't always present. In order to better train the eye, Lichess should offer puzzles that have actual tactics, such as those now, and positions that have no tactic. Users can indicate with a button perhaps if they feel a puzzle is one that falls in the "no tactic" category and earn rating there.
This would allow users to better recognize actual tactics in game,.
